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

STJ Seal-Series Lasers

The STJ Seal-Series Lasers includes both UV and green lasers with excellent beam quality and perfect spot characteristics. The whole machine adopts integrated structure design, and the optical path and external drive circuit are integrated, which makes the product have strong anti-interference ability. Optimize and upgrade the fully sealed structure to prevent external dust. At the same time, the isolation of external water molecules make the machine have strong resistance of humidity, making the SEAL series adaptable to harsher industrial environments. In addition, a self-cleaning system in the cavity allows longer lifetime of the machine.
