[0040] The implementation method of the device is as follows: multiple single-tube lasers 16 are mounted on the mounting base 1 through corresponding fixing blocks 4, and two adjacent single-tube lasers 16 are connected in series using the electrode plate 2 therebetween. In terms of the circuit, the current enters from the positive electrode from the first single-tube laser 16, flows through all the single-tube lasers 16 in sequence, and flows out from the last single-tube laser 16 to the negative electrode, and then connects to the power supply to form a loop, and the multiple single-tube lasers 16 start to work. Any water injection nozzle 11 is connected to an external cold water supply device, so that cold water flows into the water flow channel 10, and then flows out from another water injection nozzle 11 after sufficient heat exchange with the multiple single-tube lasers 16. If the first single-tube laser 16 spot is to be shaped, the light shield 3 is moved to cover the luminous area of ​​other single-tube lasers 16, and the spot of the luminous area of ​​the first single-tube laser 16 is found more quickly and accurately. The spot is adjusted to a controllable state using a three-dimensional adjustment frame and an adjustable collimating bracket 12 and a collimating lens 13. During the spot shaping process, the spot is fine-tuned forward and backward, up and down through the adjustable collimating bracket 12. When the marking line of the photolithography plate completely overlaps with the compressed spot, the glue is solidified and the spot shaping is successful. When entering the spot shaping of the next single-tube laser 16, it is only necessary to slide the slide rail 17 on the positioning seat 14 to move the second unit laser to the position of the collimating lens 13, and then use the brake to position the mounting seat 1, and adjust the light shield 3 again so that the luminous area of ​​the second single-tube laser 16 enters the collimating lens 13 to perform the spot shaping operation. The spots of other single-tube lasers 16 are shaped and compressed in the same way as above.
