Our DQ Series

Q-Switched Lasers for Surface Treatment Applications

Laser Ablation, Laser Cleaning, Insulation – the Q-switched lasers of Coherent-ROFIN are the ideal tool for these and other surface treatment applications.

 

The DQ Series, which is based on the reliable diode-pumped Nd:YAG lasers, is suitable for diverse industrial requirements. The versions differ in power, pulse energy and equipment. The unique principle of the Q-switch makes peak pulse performances possible that are a 3000 times higher than the cw laser power.
