Product Introduction

Foton Series Diode Pumped 355nm UV Lasers

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. The product is provided with either all-in-one pack or inpidual pack.
