[0034] Figure 1 FIG. 4 is a schematic diagram of a laser coupling device according to an embodiment of the present invention. Figure 2 yes Figure 1 Schematic diagram of the laser light source module. Figure 3 yes Figure 2 A partial cross-sectional schematic diagram of a laser light source module. Figure 4 FIG. 4 is a cross-sectional schematic diagram of a laser coupling device according to another embodiment of the present invention.

[0035] Please refer to Figure 1 , Figure 2 and Figure 3 The laser light source module 10 includes a first laser light source 110 (laser light source) and a first light focusing element 120 (light focusing element), and the laser coupling device 100 includes the laser light source module 10, a first light transmission element 130, a light guide element 140, a second light focusing element 150 and a second light transmission element 160. The first laser light source 110 includes a seat 111, a shell 112 and a light emitting portion 113 (shown in FIG. Figure 3 ). The shell 112 has a bottom end B and a light emitting end E opposite to each other. The bottom end B is fixed to the seat 111, and the light emitting portion 113 is disposed on the seat 111 and located inside the shell 112. The light emitting portion 113 is suitable for generating a first laser beam L1. The first light focusing element 120 is fixed to the light emitting end E of the shell 112 or the seat 111, and is located on the transmission path of the first laser beam L1. The first optical transmission element 130 is suitable for transmitting the second laser beam L2. The light guiding element 140 is disposed downstream of the optical path of the first optical transmission element 130. The second light focusing element 150 is disposed downstream of the optical path of the light guiding element 140 and the first light focusing element 120. The second optical transmission element 160 is located downstream of the optical path of the second light focusing element 150, wherein the second light focusing element 150 is suitable for coupling the first laser beam L1 and the second laser beam L2 to the second optical transmission element 160.

[0036] Please continue to refer to Figure 2 and Figure 3 , the first laser light source 110 may include a white laser light source, and the first laser beam L1 is, for example, a white laser beam. In detail, a white laser beam has a wider wavelength range than other monochromatic laser beams, so that the wavelength of the second laser beam L2 can have more choices. In this embodiment, the white laser beam can be formed by converting a blue laser beam. For example, in one embodiment, the first laser light source 110 may also include a laser light source unit 114, and the laser light source unit 114 is suitable for emitting a laser beam L. Further, the laser beam L is, for example, a blue laser beam, and the light-emitting unit 113 may be provided with a material such as a phosphor or a phosphor powder that can convert the wavelength of the laser beam to convert the laser beam L (blue laser beam) into the first laser beam L1 (white laser beam). The laser light source unit 114 may include a blue light emitting chip, but the present invention is not limited thereto. In addition, the present invention does not impose many restrictions on the specific means of generating a white laser beam. In this embodiment, the first laser light source 110 includes, for example, a white laser diode packaged in a TO-CAN package, but other embodiments are not limited thereto.

[0037] The first light-focusing element 120 of the present embodiment can guide the first laser beam L1 to the light-guiding element 140. Specifically, the first laser beam L1 generated by the light-emitting portion 113 is, for example, slightly divergent, and the first light-focusing element 120 can converge the first laser beam L1 in a divergent state, so that the first laser beam L1 can be incident on the light-guiding element 140 as a roughly parallel beam or a slightly convergent beam. The first light-focusing element 120, for example, includes a biconvex aspheric lens. In detail, because the first light-focusing element 120 is fixed to the light-emitting end E of the shell 112, the distance between the first light-focusing element 120 and the light-emitting portion 113 is greatly reduced. Therefore, the first light-focusing element 120 can adopt a biconvex aspheric lens to greatly shorten the focal length of the first light-focusing element 120, so that the first laser beam L1 can be roughly parallel beam or slightly convergent beam after passing through the first light-focusing element 120. By the way, Figure 2 and Figure 3 The structure of the biconvex aspheric lens (i.e., the first light focusing element 120) shown is only an example. Figure 4 , the first focusing element 120a of the laser coupling device 100a can be a biconvex aspheric lens, but the shape of the first focusing element 120a is different from Figure 3 The first focusing element 120. It is understood that the present invention does not impose any restrictions on the specific structure of the biconvex aspheric lens.

[0038] Please refer to Figure 1, the first light transmission element 130 can guide the second laser beam L2 to the light guide element 140. The first light transmission element 130 includes, for example, an optical fiber. Further, the optical fiber can be coupled to a second laser light source (not shown) to transmit the second laser beam L2 generated by the second laser light source to the light guide element 140. The wavelength of the second laser beam L2 can be different from the wavelength of the first laser beam L1. For example, in one embodiment, the first laser beam L1 can include a white laser beam, and the second laser beam L2 can include a red laser beam, but the present invention is not limited thereto.

[0039] In the present embodiment, the light guide element 140 can guide the second laser beam L2 emitted from the first light transmission element 130 to the second light focusing element 150. The light guide element 140 includes, for example, a prism. In other words, the light guide element 140 can include connected light guide surfaces S1, S2, and S3, wherein the light guide surface S1 can be incident on the second laser beam L2, and the light guide surface S2 can reflect the second laser beam L2 to the light guide surface S3, so that the second laser beam L2 is emitted from the light guide surface S3. In the present embodiment, the light guide surfaces S1 and S3 can be substantially perpendicular to each other, but the present invention is not limited thereto.

[0040] In the present embodiment, the second light focusing element 150 can receive the first laser beam L1 emitted from the first light focusing element 120 and the second laser beam L2 emitted from the light guide element 140, so as to converge and couple the first laser beam L1 and the second laser beam L2 to the second light transmission element 160. The second light focusing element 150 may include an aspherical lens, such as a biconvex lens, and the material of the second light focusing element 150 may include glass. Incidentally, the focal length of the second light focusing element 150 is greater than the focal length of the first light focusing element 120. On the other hand, since the second light focusing element 150 needs to be incident with the first laser beam L1 and the second laser beam L2 at the same time, the volume of the second light focusing element 150 may be greater than the volume of the first light focusing element 120.

[0041] The second optical transmission element 160 can transmit the first laser beam L1 and the second laser beam L2 coupled to each other to guide the first laser beam L1 and the second laser beam L2 coupled to each other to be emitted from the laser coupling device 100. The second optical transmission element 160 includes, for example, an optical fiber.

[0042] Compared to the prior art, the laser light source module 10 of the present embodiment adopts a first focusing element 120 to focus the first laser beam L1 generated by the first laser light source 110, wherein the first focusing element 120 is fixed to the light output end E of the shell 112 of the first laser light source 110, so as to significantly shorten the distance of the first laser beam L1 transmitted from the first laser light source 110 to the first focusing element 120. Therefore, the laser light source module 10 of the present embodiment can reduce the energy loss of the first laser beam L1, thereby improving the light utilization rate. The laser coupling device 100 of the present embodiment adopts the laser light source module 10, so as to improve the light utilization rate. In addition, since the first focusing element 120 is fixed to the shell 112 of the first laser light source 110 instead of being separated from the first laser light source 110, the space required for configuring the first focusing element 120 can be significantly reduced, thereby effectively reducing the volume of the laser coupling device 100.

[0043] Figure 5 is a schematic diagram of a laser coupling device according to another embodiment of the present invention. Figure 6 yes Figure 5 Schematic diagram of the first laser light source being separated from the shell. Figure 7 yes Figure 5 The structure and advantages of the laser coupling device 100b of this embodiment are similar to those of Figure 1 The following is an example of an embodiment of the present invention, and only the differences are described below. Please refer to Figure 5 and Figure 6 The laser coupling device 100b may further include a housing 170, an optical transmission seat 180 and a calibration component 190. The housing 170 has a first side 171, a second side 172 and a light emitting side 173. The first side 171 and the light emitting side 173 are opposite, and the second side 172 is located between the first side 171 and the light emitting side 173. The first laser light source 110 is fixed to the first side 171. Please refer to Figure 5 and Figure 7 The optical transmission seat 180 has an optical transmission portion 181 and a locking portion 182 connected to each other. The locking portion 182 is connected to the second side 172, and the optical transmission portion 181 connects the locking portion 182 and the first optical transmission element 130 (shown in FIG. Figure 7 ). The calibration assembly 190 includes a plurality of locking members 191 and a gasket 192 (also shown in FIG. Figure 6 ). The cushion member 192 is pressed between the second side 172 and the locking portion 182, and the locking member 191 passes through the locking portion 182 and the cushion member 192 and extends into the second side 172. For further information, please continue to refer to Figure 5 , light guide element 140 (drawn on Figure 1 and Figure 4) can be located in the housing 170 and close to the second side 172, and by adjusting the depth of each locking element 191 extending into the second side 172, the force of each locking element 191 pressing against the cushion 192 can be changed. In this way, the first light transmission element 130 can be slightly tilted relative to the second side 172, thereby slightly changing the angle at which the second laser beam L2 is incident on the light guide element 140.

[0044] In addition, the locking member 191 can also fix the optical transmission seat 180 to the second side 172 of the housing 170. The locking member 191 of this embodiment may include a screw. In detail, the screw may be screwed into and locked on the second side 172 first, and then slightly screwed out from the second side 172, thereby adjusting the second laser beam L2 (shown in FIG. Figure 1 and Figure 4 ) is incident on the light guide element 140 (depicted on Figure 1 ) angle. However, the present invention does not impose many restrictions on the specific operation method of the screw. Incidentally, the number of the locking members 191 of this embodiment can be at least four, which can not only improve the firmness of locking the optical transmission seat 180, but also more accurately adjust the incident angle of the second laser beam L2. The laser coupling device 100b includes four locking members 191, for example, but the present invention is not limited thereto.

[0045] Please refer to Figure 5 and Figure 7 , the gasket 192 of this embodiment includes, for example, a gasket P. Further, since the gasket P can be designed as an integral structure, it has the advantage of being easy to assemble. The gasket P can be made of a ductile material, for example, the material of the gasket P can include rubber, silicone or metal, but the present invention is not limited thereto. Incidentally, all the locking members 191 of this embodiment pass through the gasket P.

[0046] Figure 8 is a schematic diagram of a laser coupling device according to another embodiment of the present invention. Fig. 9 yes Figure 8 The structure and advantages of the laser coupling device 100c of this embodiment are similar to those of Figure 6 The following is an example of an embodiment of the present invention, and only the differences are described below. Please refer to Figure 8 and Fig. 9 , the cushion member 192c includes, for example, a plurality of cushion rings R. Specifically, the number of cushion rings R is the same as the number of locking members 191, and each locking member 191 passes through each cushion ring R and extends into the second side 172. In this way, the cushion member 192c can increase the force of pushing against each locking member 191, so as to make it easier to adjust the second laser beam L2 (shown in FIG. Figure 1 and Figure 4 ) is incident on the light guide element 140 (depicted on Figure 1 and Figure 4Similarly, the material of the gasket ring R includes, for example, rubber, silicone or metal, but other embodiments are not limited thereto.

[0047] Fig.10 It is a schematic diagram showing that a housing, a light transmission seat, a calibration assembly and a first light transmission element of a laser coupling device according to another embodiment of the present invention are separated from each other. Fig.11 yes Fig.10 The structure and advantages of the laser coupling device 100d of this embodiment are similar to those of FIG. Fig. 9 The following is an example of an embodiment of the present invention, and only the differences are described below. Please refer to Fig.10 and Fig.11 The second side 172d of the housing 170d may have a plurality of grooves G. The gaskets R are respectively disposed in the grooves G, and a portion RP of each gasket R protrudes from each groove G. The locking portion 182 is pressed against the portion RP of the gasket R, so that the gasket R can be more firmly fixed to the second side 172d when pressed by the locking portion 182. It can be understood that the number of the grooves G is the same as the number of the gaskets R.

[0048] Fig.12 is a schematic diagram of a laser coupling device according to another embodiment of the present invention. The structure and advantages of the laser coupling device 100e of this embodiment are similar to those of Figure 1 The following is an example of an embodiment of the present invention, and only the differences are described below. Please refer to Fig.12 , the laser coupling device 100e may further include a light homogenizer D, which is disposed between the second focusing element 150 and the second optical transmission element 160. In detail, the light homogenizer D can block the stray light of the first laser beam L1, and homogenize the light spot of the first laser beam L1, so that the first laser beam L1 can be more evenly and concentratedly incident on the second optical transmission element 160. In this way, the light collecting effect of the second optical transmission element 160 can be effectively improved, thereby further improving the light utilization rate of the laser coupling device 100e. By the way, the light homogenizer D may include an atomized quartz light homogenizer, and in one embodiment, the thickness of the atomized quartz light homogenizer may be approximately 1 mm, but the present invention does not impose further restrictions on this.

[0049] Fig.13 FIG. 1 is a partial cross-sectional schematic diagram of a laser light source module of a laser coupling device according to another embodiment of the present invention. The structure and advantages of the laser coupling device 100f of this embodiment are similar to those of the laser light source module 10f. Figure 1 The following is an example of an embodiment of the present invention, and only the differences are described below. Please refer to Fig.13, the first light focusing element 120f is fixed to the seat 111 and covers the light emitting portion 113. The laser light source portion 114 is fixed to the seat 111 of the first laser light source 110, and is suitable for emitting a laser beam L toward the first light focusing element 120f. The first light focusing element 120f is suitable for focusing the laser beam L to the light emitting portion 113, and the light emitting portion 113 is suitable for converting the laser beam L into a first laser beam L1. Specifically, the laser beam L can be focused to the light emitting portion 113 by the first light focusing element 120f, and the distance between the first light focusing element 120f and the light emitting portion 113 is greatly shortened, so that more first laser beams L1 emitted from the light emitting portion 113 are incident on the first light focusing element 120f, thereby further improving the light utilization rate. In addition, since the laser beam L can be incident on the light emitting portion 113 more concentratedly through the first light focusing element 120f, and the distance between the first light focusing element 120f and the light emitting portion 113 is greatly shortened, the first laser beam L1 can be made closer to a parallel beam and emitted from the shell 112. In this way, the messy light spots generated by the reflection of the first laser beam L1 inside the shell 112 can be reduced or eliminated, thereby reducing the generation of stray light. For example, the laser coupling device 100f of this embodiment can be omitted Fig.12 In this embodiment, the first light focusing element 120f may include a concave-convex lens, but the present invention is not limited thereto.

[0050] In summary, the laser light source module of the present invention uses a first focusing element to focus the first laser light beam generated by the first laser light source, wherein the first focusing element is fixed to the light-emitting end of the shell of the first laser light source, so as to significantly shorten the distance that the first laser light beam is transmitted from the first laser light source to the first focusing element. Therefore, the laser light source module of the present invention can reduce the energy loss of the first laser light beam, thereby improving the light utilization rate. The laser coupling device of the present invention uses the above-mentioned laser light source module, so it can improve the light utilization rate. In addition, since the first focusing element is fixed to the shell of the first laser light source instead of being separated from the first laser light source, the space required for configuring the first focusing element can be significantly reduced, thereby effectively reducing the volume of the laser coupling device.
