High Pulse Energy Air-cooled DPSS Nd:YAG Laser
High Pulse Energy Air-cooled DPSS Nd:YAG Laser QX500

SOLAR LS presents a new model of completely air-cooled pulsed diode-pumped Nd:YAG laser.

The QX500 delivers 160 mJ at 1064 nm in nanosecond pulses at repetition rates up to 20 Hz.

  • High-power output of 160 mJ at 20 Hz
  • Air cooling – no water required
  • Smooth flat-top beam profile
  • VIS and UV harmonic generators
  • OEM/Industrial design for 24/7 operation
  • Long diode lifetime over 1 billion shots
  • Turn-key operation


The QX500 laser features long-life laser diode bars and delivers excellent pulse-to-pulse and long-term stability which is ideally suited for use in scientific, industrial, and medical applications. Diode pumping reduces size, improves reliability, and eliminates most maintenance operations.

Minimum service costs are conditioned by optical pumping using laser diode bars with more than 109 pulses lifetime.

Stability of the parameters and the laser reliability are guaranteed due to dustproof housing design and thermal stabilisation of the optical cavity.

The possibility of operation in the VIS and UV spectral range thanks to small external harmonic generators will expand your opportunities.

Compact laser design and complete air cooling not only simplify application of this device as a stand-alone unit, but also allow to integrate it into any equipment.
