Product Introduction

In order to meet the requirements of precise processing in industrial, we developed a 355nm end-pumped Q-switched laser. The adoption of water cooled system allows laser source to have stable performance, smaller size, compact structure and low power consumption. The output laser beam is the fundamental mode, the beam quality is good, and the peak power is high, which can meet most industrial precision processing requirements.

Features:

Thanks to the integrated design, the product has compact structure, small size, light weight, low power consumption, stable operation over time and good beam quality. The laser’s driver has a simple design and a user-friendly operation interface. It is extremely convenient for user to install and debug it, besides user also can adjust and control the laser power and repetition frequency output at any time in order to meet various need.
