Technical Field

[0001] This utility model relates to the technical field of laser detection, and more specifically, to a laser. Background Technology

[0002] In existing laser technologies, when detecting the power of the laser incident on the coupler or the collimation effect of the collimation component, corresponding power detection equipment and collimation detection equipment are required. This is not only costly, but also complex to operate and requires a large amount of work. Utility Model Content

[0003] The purpose of this invention is to provide a laser that solves the technical problem in the prior art of requiring specialized testing equipment to detect the incident laser power or collimation effect of the laser coupler.

[0004] The laser provided by this utility model includes a base and a coupler and a detection component disposed on the base. The coupler includes a housing and a collimation component and a beam splitter component disposed inside the housing and arranged sequentially along the main transmission direction of the laser. The housing is provided with a perforation, and the light reflected by the beam splitter component can be emitted through the perforation. The detection component is used to detect the power and / or the spot shape of the light reflected by the beam splitter component and emitted through the perforation.

[0005] The coupler also includes a light-shielding plate, which is detachably disposed on the housing and used to close or open the perforation.

[0006] Furthermore, the detection component includes a power meter for detecting the power of light reflected by the beam splitter and emitted through the aperture.

[0007] Furthermore, the beam splitting assembly includes a beam splitter base and a beam splitter mirror mounted on the beam splitter base. The housing includes a base plate. One of the beam splitter base and the base plate is provided with a positioning post, and the other is provided with a positioning hole. The positioning post and the positioning hole are matched and inserted into each other.

[0008] Furthermore, the detection component includes a detection plate, which is provided with a standard light spot, and the standard light spot covers a preset target range of light reflected by the beam splitter and emitted through the perforation.

[0009] Furthermore, the housing includes a first side plate, the perforation is disposed on the first side plate, and the light shield is disposed outside the first side plate.

[0010] Furthermore, the housing also includes a second side plate disposed adjacent to the first side plate, and the light shield extends to be provided with a first positioning wing plate. When the light shield is attached to the first side plate and closes the perforation, the first positioning wing plate is attached to the second side plate.

[0011] Furthermore, the light-shielding plate is also provided with a second positioning wing plate, which is used to fix the coupler to the base.

[0012] Furthermore, the detection component is detachably mounted on the base.

[0013] Furthermore, the base is provided with a first detection position for mounting the power meter of the detection component.

[0014] Furthermore, the base is provided with a second detection position for mounting the detection plate of the detection component.

[0015] The laser provided by this utility model has the following beneficial effects:

[0016] The laser provided by this invention features a detection component mounted on a base. A perforation is made in the coupler's housing, and a light-shielding plate is installed. During detection, the light-shielding plate is opened through the perforation, allowing light reflected from the beam splitter to exit through the perforation. The detection component then detects the reflected light. Preferably, the detection component of the laser provided by this invention can detect both the power and the shape of the reflected light spot. Since the collimation component is considered to consume no power, if the power detected by the detection component matches the theoretical power value or is within the allowable error range, it indicates that the incident light power meets the requirements. Otherwise, the devices before the collimation component need to be adjusted to ensure the incident light meets the requirements. If the light spot detected by the detection component matches the standard light spot (a standard spot used for reference) or is within the allowable error range, it indicates that the collimation effect of the collimation component on the incident light from the coupler meets the requirements. Otherwise, the collimation component needs to be adjusted until its collimation effect meets the requirements.

[0017] In summary, the laser provided by this utility model, by opening a perforation in the housing of the coupler and setting a detection component on the base of the laser, can detect the power of the incident light of the laser and the collimation effect of the collimation component. It is easy to operate and has a simple structure.

[0018] Furthermore, if the collimation effect of the collimation component meets the requirements, or meets the requirements after adjustment, but the error of the coupler's output light is still too large and does not meet the requirements, the error of the coupler's output light can be quickly and accurately ruled out as being caused by the collimation component, thereby narrowing down the scope of the error location. Moreover, compared to directly adjusting the collimation component to reduce the error of the coupler's output light, this invention can effectively avoid the situation of erroneous adjustment of the collimation component.

[0036] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0037] This embodiment provides a laser, such as Figures 1 to 3 as well as Figure 5 and Figure 6 As shown, the laser includes a base 100 and a coupler 200 and a detection component disposed on the base 100. The coupler 200 includes a housing 210 and a collimation component 220 and a beam splitter component 230 disposed within the housing 210 and arranged sequentially along the main transmission direction of the laser. The housing 210 is provided with a perforation 211, through which the light reflected by the beam splitter component 230 can be emitted. The detection component is used to detect the power and / or spot shape of the light reflected by the beam splitter component 230 and emitted through the perforation 211. The coupler 200 also includes a light shield 240, which is detachably disposed on the housing 210 and used to close or open the perforation 211.

[0038] The laser provided in this embodiment has a detection component mounted on a base 100. A perforation 211 is formed in the housing 210 of the coupler 200, and a light-shielding plate 240 is installed. During detection, the light-shielding plate 240 is opened through the perforation 211, allowing light reflected from the beam splitter 230 to exit through the perforation 211. The detection component can then detect the reflected light. Preferably, the detection component of the laser provided in this embodiment can detect both the power and the shape of the reflected light spot. Since the collimation component 220 is considered to consume no power, if the power detected by the detection component matches the theoretical power value or is within the allowable error range, it indicates that the incident light power meets the requirements. Otherwise, the devices before the collimation component 220 need to be adjusted to ensure the incident light meets the requirements. If the light spot detected by the detection component matches the standard light spot 410 or is within the allowable error range, it indicates that the collimation effect of the collimation component 220 on the incident light from the coupler 200 meets the requirements. Otherwise, the collimation component 220 needs to be adjusted until its collimation effect meets the requirements.

[0039] In summary, the laser provided in this embodiment, by opening a perforation 211 in the housing 210 of the coupler 200 and setting a detection component in the base 100 of the laser, can detect the power of the incident light of the laser and the collimation effect of the collimation component 220. It is easy to operate and has a simple structure.

[0040] Furthermore, if the collimation effect of the collimation component 220 meets the requirements, or meets the requirements after adjustment, but the error of the emitted light from the coupler 200 is still too large and does not meet the requirements, the error of the emitted light from the coupler 200 can be quickly and accurately ruled out as being caused by the collimation component 220, thereby narrowing down the scope of the error location. Moreover, compared to directly adjusting the collimation component 220 to reduce the error of the emitted light from the coupler 200, this embodiment can effectively avoid the situation of erroneous adjustment of the collimation component 220.

[0041] Specifically, in this embodiment, as Figure 5 and Figure 6 As shown, the detection component includes a power meter 300, which is used to detect the power of light reflected by the beam splitter 230 and emitted through the aperture 211.

[0042] More specifically, in this embodiment, the detection component is detachably mounted on the base 100. The base 100 is provided with a first detection position for mounting the power meter 300 of the detection component, and the power meter 300 is detachably mounted on the first detection position. In this configuration, when it is necessary to detect the power of the incident light of the coupler 200, that is, when it is necessary to detect the power of the light reflected by the beam splitter 230 and emitted through the perforation 211, the power meter 300 can be mounted on the first detection position for detection; after the detection is completed, the power meter 300 can be removed for detection of other lasers. Of course, after the detection is completed, the power meter 300 can also be left in place for the next detection.

[0043] Specifically, in this embodiment, as Figure 5 and Figure 6 As shown, the detection component includes a detection plate 400, which is provided with a standard light spot 410. The standard light spot 410 covers a preset target range of light reflected by the beam splitter 230 and emitted through the perforation 211, and is used to detect the collimation effect of the collimation component 220.

[0044] In this embodiment, the installation error of the beam splitter 230 is negligible. Preferably, the beam splitter 230 has the required installation accuracy through a positioning structure. Specifically, for example... Figure 4As shown, the beam splitter assembly 230 includes a beam splitter base 231 and a beam splitter 232 mounted on the beam splitter base 231. The housing 210 includes a base plate 212. One of the beam splitter base 231 and the base plate 212 is provided with a positioning post 233, and the other is provided with a positioning hole 213. The positioning post 233 and the positioning hole 213 are matched and inserted. More specifically, in this embodiment, the positioning post 233 is provided on the beam splitter base 231, and the positioning hole 213 is provided on the base plate 212 of the housing 210. Of course, in other embodiments of this application, the positions of the positioning post 233 and the positioning hole 213 are not limited to the above positions. For example, the positioning post 233 can also be provided on the base plate 212 of the housing 210, and the positioning hole 213 can be provided on the beam splitter base 231. That is, as long as the beam splitter assembly 230 can play the required positioning role, this application does not limit the specific position of each positioning structure, nor does it limit the specific form of the positioning structure.

[0045] When the installation error of the beam splitter 230 is negligible, the collimation effect of the collimation component 220 can be detected more accurately. If the light spot reflected by the beam splitter 230 and emitted through the perforation 211 is within the coverage of the standard light spot 410, the collimation effect of the collimation component 220 can be determined to meet the requirements; otherwise, the collimation effect of the collimation component 220 is determined to not meet the requirements. At that time, the collimation component 220 needs to be adjusted until the collimation effect of the collimation component 220 meets the requirements.

[0046] Specifically, in this embodiment, the base 100 is provided with a second detection position for mounting the detection plate 400 of the detection component. The detection plate 400 is detachably mounted in the second detection position. With this configuration, when it is necessary to test the collimation effect of the light collimated by the collimation component 220, that is, to test the collimation effect of the light reflected by the beam splitter 230 and emitted through the perforation 211, the detection plate 400 can be mounted in the second detection position for testing. After the test is completed, the detection plate 400 can be removed for testing other lasers; alternatively, the detection plate 400 can remain in place for the next test.

[0047] Whether detecting the power of the light reflected by the beam splitter 230 and emitted through the perforation 211, or detecting the collimation effect of the collimation assembly 220, it is necessary to open the perforation 211 in the light-shielding plate 240. In this embodiment, as... Figure 1 and Figure 2 As shown, the housing 210 of the coupler 200 includes a first side plate 214, a through hole 211 is provided on the first side plate 214, and a light shield 240 is provided outside the first side plate 214.

[0048] Specifically, in this embodiment, as Figure 2As shown, the housing 210 also includes a second side plate 215 disposed adjacent to the first side plate 214. The light shield 240 extends and is provided with a first positioning wing plate 241. When the light shield 240 is attached to the first side plate 214 and the through hole 211 is closed, the first positioning wing plate 241 is attached to the second side plate 215. In this configuration, the first positioning wing plate 241 positions the light shield 240 in a direction perpendicular to the second side plate 215. When installing the light shield 240, by attaching the first positioning wing plate 241 to the second side plate 215, the light shield 240 can be quickly attached to the first side plate 214 and the through hole 211 can be closed.

[0049] Specifically, in this embodiment, the following continues... Figure 2 As shown, the light-shielding plate 240 also extends with a second positioning wing plate 242, which is used to fix the coupler 200 to the base 100. In this configuration, the second positioning wing plate 242 positions and fixes the light-shielding plate 240 in a direction perpendicular to the base 100. During installation, the first positioning wing plate 241 is made to fit against the second side plate 215, the second positioning wing plate 242 is made to fit against the base 100, and the light-shielding plate 240 is made to fit against the first side plate 214. The second positioning wing plate 242 is then fixed to the base 100, thus installing the light-shielding plate 240 in place. This is very convenient and quick, and it is easy to install and remove the light-shielding plate 240, as well as to open and close the perforation 211.

[0050] In summary, this embodiment provides a laser in which the housing 210 of the coupler 200 is provided with a perforation 211, which allows light that enters from the pump source interface 201 of the coupler 200, is collimated by the collimating component 220 inside the coupler 200, and is reflected by the beam splitting component 230 to be emitted. The laser in this embodiment also has a detection component detachably provided on the base 100, specifically including a power meter 300 and a detection plate 400. The former can detect the power of the light emitted from the perforation 211, thereby detecting whether the power of the incident light of the coupler 200 meets the requirements. The latter can detect the light spot of the light emitted from the perforation 211, thereby detecting the collimation effect of the collimating component 220. Compared with the prior art of detecting the light emitted from the light outlet 202 of the coupler 200, no special power detection equipment and collimation detection equipment are required, resulting in low cost, simple structure, and convenient operation.

[0051] Of course, the laser provided in this embodiment, such as Figure 1 As shown, the base 100 is also equipped with a power supply 500 and a PCB (Printed Circuit Board) 600, which are the same as those in the prior art and will not be described in detail here.
