[0002] In a laser device system, the role of a PC drive power supply is to provide high-precision and high-stability high-voltage electrical pulses to drive the Pockels cell to work. The Pockels cell realizes the modulation and control of the laser through the electro-optic effect.

[0003] However, the existing PC drive power supply, Pockels cell, and Pockels cell attitude adjustment mechanism are produced by different manufacturers. When the end customer installs and uses them, the three products need to be installed and debugged separately, which takes 3 times of installation and debugging time. All three products need to reserve separate installation spaces in the laser device, resulting in a large space requirement. There is a certain distance between the PC drive power supply and the Pockels cell, resulting in certain losses of cable signals and a certain reduction in laser energy.

[0004] All three products are manually debugged after installation, and subsequent fine-tuning also requires opening the cover of the laser device.
