Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0044] The following describes a multi-wavelength laser provided by an embodiment of this utility model with reference to the accompanying drawings. Figure 2-8 The multi-wavelength laser includes a control box 10 and a laser box 20.
[0045] refer to Figure 3 The control box 10 includes a main control board 110 and at least one driver 120, with the input terminal of the at least one driver 120 electrically connected to the main control board 110. The main control board 110 sends control signals to the driver 120 in response to user operation. The driver 120 outputs electrical signals to the laser source 230 in response to the control signals, thereby driving the laser source 230 to turn on and emit a laser beam. The main control board 110 can also be used to transmit control signals from the optical path switching output component 240 to the laser box 20.
[0046] In some implementations, the main control board 110 can be electrically connected to each driver 120 via an RS485 communication bus to achieve specific control of each laser.
[0047] refer to Figure 5-6The laser box 20 includes a first housing 250, a light outlet 280 and a control interface 210 exposed in the first housing 250, and a laser box control board 220, a mounting plate 290, an optical path switching output component 240 and at least two laser sources 230 capable of emitting at least two wavelength laser beams disposed in the first housing 250. The at least two laser sources 230 are integrated on the mounting plate 290. The output terminal of at least one driver 120 and the input terminal of the laser box control board 220 are electrically connected through the control interface 210. The output terminal of the laser box control board 220 is electrically connected to each laser source 230 and the optical path switching output component 240 respectively.
[0048] Specifically, the first housing 250 encapsulates the laser box control board 220, the laser source 230, and the optical path switching output component 240. The mounting plate 290 has at least two light source mounting positions, and the laser source 230 is detachably mounted on one of these positions for easy replacement. Preferably, the number of light source mounting positions is greater than or equal to the number of currently integrated laser sources 230, allowing for flexible expansion of the laser source 230.
[0049] Specifically, the at least two laser sources 230 may include at least two wavelengths of laser source 230. Preferably, the wavelengths of the laser beams emitted by each laser source 230 are different from each other, and the selectable wavelengths are not limited.
[0050] Specifically, the laser box control board 220 is used to cooperate with the control signals of the main control board 110, transfer them to the drive circuits of each laser source 230, and control the movement and switching of the optical path switching output component 240. During operation, the laser source control board 220 can receive the control signals from the main control board 110 and the drive electrical signals from the driver 120 through the control interface 210, so as to control the optical path switching output component 240 to switch to the optical path of the currently required laser source 230 in response to the control signals, and transmit the drive electrical signals to the drive circuit of the laser source 230, so that the laser source 230 turns on and emits a laser beam of the required wavelength, thereby realizing the control of laser sources 230 with different wavelengths and powers and the output of laser beams.
[0051] The optical path switching output component 240 can move relative to the mounting plate 290 to switch the optical path to each laser source 230. The laser beams emitted from at least two laser sources 230 can be output collinearly to the output port 280 after passing through the optical path switching output component 240.
[0052] Specifically, refer to Figure 4-6 and Figure 8 The optical path switching output component 240 can move and switch to the optical path of each laser source 230 to project the laser beam of the laser source 230 to the output port 280, forming a beam L of the laser box 20. The output optical paths formed by the laser beams of each laser source 230 after being projected by the optical path switching output component 240 are in the same line.
[0053] In summary, by setting up a laser box 20 to integrate at least two laser sources 230 capable of emitting at least two wavelengths of laser light, and setting up a control box 10 to integrate at least one driver 120 capable of driving each laser source 230 in the laser box 20, and by setting up a laser box control board 220 and a control interface 210 in the laser box 20, and setting up a main control board 110 in the control box 10, the main control board 110 of the control box 10 is used as a single control node to control multiple laser sources 230 in the laser box 20, thereby realizing the integration of multi-wavelength laser sources 230 and control, reducing the complexity of equipment structure, control complexity, and equipment cost, simplifying user operation, and facilitating the flexible expansion of the number and model of laser sources 230. In addition, the laser box 20 is also provided with an optical path switching output component 240, which switches on the output optical path of each laser source 230 by moving to achieve collinear output of the laser beams of each laser source 230. Compared with the traditional method of output beams through multiple dichroic mirrors, the structure of this application significantly reduces light intensity loss and improves light utilization.
[0054] Understandably, compared to laser systems that integrate multiple individual lasers, such as Figure 1 and Figure 2 As shown, when the multi-wavelength laser of this application integrates N laser sources 230, it can reduce the number of control boxes 10, laser boxes 20 and main control boards 110 by N-1, greatly reducing the complexity of the system structure. The more types of wavelengths or power of the laser sources 230 required, the more obvious its advantages become.
[0055] In some implementations, reference is made to Figure 3 and Figure 4 The control box 10 also includes a second housing, in which the driver 120 and the main control board 110 are disposed; the control box 10 also includes at least one of the human-machine interface 130 and the host computer interface 140 exposed to the second housing, for connecting to an external control node device, thereby realizing the control of multiple laser sources 230 through the external control node.
[0056] In some implementations, reference is made to Figure 3 and Figure 4 The driver 120 is configured to correspond one-to-one with the laser source 230. Specifically, the laser box control board 220 integrates the control circuits of each laser source 230, and the output of the driver 120 is electrically connected to the control circuit of a single laser source 230 on the laser box control board 220 through the control interface 210, so as to realize the independent control of each laser source 230.
[0057] In other embodiments, at least some of the drivers 120 are configured to be coupled to at least two laser sources 230, with the at least two laser sources 230 coupled to a single driver 120 connected in parallel. Specifically, the output of the driver 120 is electrically connected via a control interface 210 to the control circuits of at least two laser sources 230 on the laser box control board 220, so as to improve the drive integration of the control box 10 and reduce the size of the control box 10 by driving two or more laser sources 230 separately with a single driver 120. In one embodiment, the number of at least one driver 120 is at least two, and at least some of the drivers 120 are configured to be coupled to at least two laser sources 230.
[0058] In some embodiments, the drive device 243 includes an electrically connected drive mechanism 2431 and a drive controller 2432. The drive controller 2432 is electrically connected to the laser box control board 220 to receive control signals. The drive mechanism 2431 is drivenly connected to the motion mechanism 242, and the drive mechanism 2431 can respond to the drive signal from the drive controller 2432 to drive the motion mechanism 242 and the reflector 241 to switch optical paths.
[0059] In some implementations, reference is made to Figure 5 At least two laser sources 230 are arranged adjacent to each other in sequence to reduce the space occupied by the laser sources 230 on the mounting plate 290, thereby reducing the size of the laser box 20.
[0060] In some implementations, at least two laser sources 230 are arranged in parallel with their optical paths spaced apart. The laser beams emitted from each laser source 230 are emitted along parallel optical paths, which is beneficial for the positional arrangement of each laser source 230 and simplifies the modulation of each laser beam, thereby improving the collinear output accuracy of each laser source 230.
[0061] In some implementations, reference is made to Figure 4-5 The laser box 20 also includes a guide light source 260 disposed within the first housing 250. The guide light source 260 is mounted on the mounting plate 290 and electrically connected to the output terminal of the laser box control board 220. The optical path switching output component 240 is movable to switch between the optical paths of each laser source 230 and the optical path of the guide light source 260, thereby achieving alignment with the laser beam projection optical path and the guide light projection optical path. The laser beams emitted from at least two laser sources 230 and the guide beam emitted from the guide light source 260 can be collinearly output to the light outlet 280 after passing through the optical path switching output component 240. The guide light source is used to emit a guide beam, which is visible light and can be used to adjust the projection position of the laser beam, achieving precise positioning of the laser beam in the projection area. This facilitates the adjustment and operation of invisible light sources such as near-infrared and mid-infrared, improving the safety of equipment use.
[0062] In some embodiments, reference is made to Figure 5 The guide light source 260 and the laser source 230 are arranged adjacent to each other, and the guide light source 260 and the laser source 230 avoid each other's outgoing light paths, further optimizing the light source occupancy.
[0063] Understandably, in conjunction with the optical path switching output component 240, the placement of the guide light source 260 is unrestricted; for example, it can be placed between or to one side of each laser source 230, improving assembly flexibility. Preferably, the guide light source 260 is placed on the side of each laser source 230 closer to the light outlet 280, that is, the guide light source 260 is closer to the light outlet 280 than the laser sources 230, to facilitate the integrated assembly, beam modulation, and calibration of the laser sources 230.
[0064] In some embodiments, the outgoing light paths of the guide light source 260 and each laser source 230 are arranged at intervals and parallel to each other.
[0065] In some implementations, reference is made to Figure 5 The laser box 20 also includes an optical path component 270 disposed within the first housing 250. The optical path component 270 is disposed between the laser source 230 and the optical path switching output component 240. The laser beam emitted from the laser source 230 can be projected onto the optical path switching output component 240 after passing through the optical path component 270, and finally achieves collinear output of all laser sources 230.
[0066] In some implementations, reference is made to Figure 8 The optical path assembly 270 includes at least two first optical path adjustment mechanisms 271, each corresponding to a laser source 230. The laser beam emitted from the laser source 230 is projected onto the optical path switching output assembly 240 after passing through the first optical path adjustment mechanism 271. The first optical path adjustment mechanism adjusts the incident laser beam to ensure that the emitted laser beam can be projected onto the optical path switching output assembly 240. Preferably, the first optical path adjustment mechanism 271 is fixedly disposed in the output optical path of the laser source 230.
[0067] In some implementations, reference is made to Figure 8 The optical path assembly 270 also includes a second optical path adjustment mechanism 272, which is disposed between the guide light source 260 and the optical path switching output assembly 240. The guide light emitted from the guide light source 260 is projected onto the optical path switching output assembly 240 after passing through the second optical path adjustment mechanism 272. Specifically, the second optical path adjustment mechanism 272 is used to receive and project the guide beam. The optical path switching output assembly 240 can move to the output optical path of the second optical path adjustment mechanism 272 to achieve optical path alignment and realize the collinear output of the guide beam and the laser beam.
[0068] In some embodiments, the laser beams emitted through each of the first adjustment optical path mechanisms 271 are spaced apart and parallel to each other.
[0069] In some embodiments, the laser beams emitted through the first optical path adjustment mechanism 271 and the guide beams emitted through the second optical path adjustment mechanism 272 are spaced apart from each other and parallel.
[0070] In other embodiments, refer to Figure 9 The optical path assembly 270 includes a first optical path adjustment mechanism 271, which can move in coordination with the optical path switching output assembly 240 to switch the optical path to each laser source 230. Specifically, the first optical path adjustment mechanism is movably disposed within the first housing 250 and can move in coordination with the optical path switching output assembly 240 relative to the laser source 230 in response to a control signal, forming a movable projection optical path for each laser source 230, thereby simplifying the optical path assembly 270 and reducing costs.
[0071] In some embodiments, when a guide light source 260 is present, the first optical path adjustment mechanism 271 and the optical path switching output component 240 can move in coordination to switch between the optical paths of each laser source 230 and the optical path of the guide light source 260, thereby forming a movable aligned projection optical path for the guide light source 260 through the first optical path adjustment mechanism 271 and the optical path switching output component 240, and ensuring the colinearity of the guide beam and the laser beam.
[0072] In some implementations, reference is made to Figure 5 The optical path switching output component 240 includes a reflector 241, a motion mechanism 242 connected to the reflector 241, and a drive device connected to the motion mechanism 242. The drive device is electrically connected to the laser box control board 220. The drive device can drive the motion mechanism 242 to move, thereby causing the reflector 241 to move linearly relative to the mounting plate 290. The optical paths of at least two laser sources 230 are located on the linear movement path of the reflector 241. The laser box control board 220 can control the operation of the drive device in response to the control signal of the main control board 110, so that the motion mechanism 242 moves in conjunction with the reflector 241 to the optical path of the laser beam to be emitted, and reflects the laser beam of the required wavelength to the output port 280. Compared with the traditional method of emitting the beam through multiple dichroic mirrors, this significantly reduces light intensity loss, improves light utilization, and avoids the limitation of wavelength selection of the laser source 230, enabling flexible adaptation to laser beams of various wavelengths. Meanwhile, the linear motion of the reflector 241 ensures laser switching and collinear output between different laser sources 230, improving the movement control precision of the reflector 241 and reducing the difficulty of adjusting the optical path of the emitted laser beam. In one embodiment, the reflector 241 is a total reflection mirror.
[0073] In some embodiments, a first optical path adjustment mechanism 271 is provided, corresponding one-to-one with each laser source 230. A motion mechanism 242 drives a reflector 241 to move relative to each first optical path adjustment mechanism 271 to receive the laser beam emitted from each first optical path adjustment mechanism 271. In other embodiments, the first optical path adjustment mechanism 271 and the optical path switching output component 240 can move together. The motion mechanism 242 is connected to the first optical path adjustment mechanism 271. The motion mechanism 242 can drive the reflector 241 and the first optical path adjustment mechanism 271 to move together, so as to accurately switch the optical path to different laser sources 230. This allows the laser beam in the optical path to be projected onto the reflector 241 through the first optical path adjustment mechanism 271 and then reach the output port 280 through the collinear output optical path. By moving the reflector 241 and the first optical path adjustment mechanism 271 together through the motion mechanism 242, the accuracy of optical path alignment can be improved and the difficulty of optical path calibration and adjustment can be reduced.
[0074] In some embodiments, the first adjusting optical path mechanism 271 forms a reflected optical path for the projected laser beam. Preferably, the first adjusting optical path mechanism 271 forms a total internal reflection optical path for the projected laser beam, that is, a total internal reflection mirror is used as the adjusting element in the adjusting optical path, so that the entire optical path of the laser beam adopts reflection transmission, which significantly reduces light energy loss and can be adapted to lasers of any wavelength.
[0075] In some embodiments, the second adjusting optical path mechanism 272 forms a reflected optical path for projecting the guide beam. Preferably, the second adjusting optical path mechanism 272 forms a total internal reflection optical path for projecting the guide beam, which significantly reduces light energy loss while being adaptable to light sources of any wavelength, and ensures the transmission consistency between the guide beam and the laser beam, which helps to simplify optical path assembly and reduce calibration difficulty.
