Abstract

The invention discloses a femtosecond laser processing device. In the laser optical path direction, a femtosecond laser device, a horizontal optical path device, a vertical optical path device, a laser processing device and a processing platform are sequentially included. The diameter of light spots of a laser is reduced through utilization of the femtosecond laser device. A probe is arranged in the horizontal optical path device, and a mini-type camera is arranged in the laser processing device, so that the states of a laser beam and a sample are observed in real time. A first reflector, a second reflector, a third reflector, a fourth reflector and a fifth reflector are arranged in the horizontal optical path device so that devices, located among the reflectors, in the horizontal optical path device can be reasonably arranged, and the structure of the processing device is more compact. Sliding platforms in the X direction, the Y direction and the Z direction are arranged on the processing platform so that the processing platform can be moved and adjusted in the processing process.

Description

technical field [0001] The invention relates to the field of laser processing, in particular to a femtosecond laser processing device. Background technique [0002] With the improvement of laser processing technology and the expansion of application range, laser processing is becoming more and more popular in production activities. The optical path and the processed sample are observed in real time. There are many optical components in the laser processing device, which are fixed in position, occupy a large space, and are not easy to move. Most of the processing platforms are single and fixed, with no adjustment function. The digital control of processing parameters, processing process and laser parameters cannot be realized, and most of them can only process simple plane graphics, and the processing efficiency is low. Contents of the invention [0003] For this reason, it is necessary to provide a femtosecond laser processing device to solve the problem that the current ...
