Nd:YAG DPSS Laser Systems

General Information

ND-series DPSS Nd:YAG Q-switched laser systems are represented by air-cooled and water-cooled models. Water-cooled lasers offer high repetition rates up to 100Hz. Air-cooled are limited by 20Hz level but can operate in conditions where size is critical or liquid cooling is impossible.

Systems consist of an industrial grade stabilized aluminum laser head and compact power supply. Thanks to their compact size and misalignment-free design, lasers can be easily integrated into customer’s devices and operate in 24/7 mode.
All DPSS systems provide perfect beam quality and long term energy stability.
Nd:YLF based modifications with 1047 or 1053 nm output are available as options.
Detachable or embedded automatically switched harmonics generators up to fifth are also available.
