DPSS active Q-switched lasers from CrystaLaser.

A compact, active Q-Switched, pulsed laser with superior performance. The Q-Switched Series’ breakthrough technology enables optimum performance with the lowest power consumption available. The design is flexible enough for both the repetition rate and pulse width requirements of your application.

 

Features:

  • Wavelength 262 nm to 1340 nm, power up to 4 W
  • Excellent beam quality
  • Extremely low power consumption
  • Air-cooled – no cooling water or fan required
  • Unmatched ultra-compact and ultra-light-weight
  • Repetition rate 1 kHz to 100 kHz internal adjustment, 0 Hz to 200 kHz by external trigger

 

Applications:

  • Material processing
  • Semiconductor inspection
  • LIDAR
  • Photoluminescence
  • Solar material processing
  • Scientific research
  • Raman spectroscopy
