Optical shaping method and system for semiconductor laser

The invention discloses an optical shaping method and an optical shaping system for a semiconductor laser. The method comprises the following steps of: arranging an indicator board on which light spot standard scales are calibrated at a certain fixed position; a shaping lens group is used for shaping a light beam emitted by a certain laser chip of the semiconductor laser, and the spatial position of the shaping lens group is adjusted, so that a shaped light spot is displayed on the indicator board and is consistent with the standard scale of the light spot; curing the shaping lens group to lock the spatial position of the lens group corresponding to the current laser chip so as to complete beam shaping of the chip; and repeating the steps until the beam shaping of all laser chips of the semiconductor laser is completed, so as to obtain the required optical spot. According to the optical shaping method provided by the invention, customization of various light spot requirements can be realized through one devic
