Q-switched Laser, Compact DPSS Q-switched Nd:YAG Nd:YLF lasers

Diode Pumped Ultra-compact Q-switched Lasers

UV to IR Ultra-compact TEMoo High efficiency High reliability

  • CrystaLaser designs and manufactures state of the art ultra-compact diode-pumped Nd:YAG, Nd:YVO4 and Nd:YLF crystal lasers. Our lasers feature with low noise, high stability, high efficiency, high reliability and excellent laser beam quality. The specific designed compact Q-switched laser with low jitter is great for LIDAR application and the Q-switched IR, green and UV lasers are suitable for laser trimming, marking and micro machining application in semiconductor industry. These lasers are suitable for OEM, scientific and industrial use.
  • Compact Q-switched pulsed laser
  • Current available Q-switched laser products include diode-pumped solid-state Nd:YAG, Nd:YVO4 and Nd:YLF Q-switched laser systems.
  • New Product !!
  • Wavelengths of the Q-switched laser available from UV to IR (nm):
    262, 266, 349, 351, 355, 440, 447, 473, 523, 527, 532, 555, 561, 589, 593, 660, 671, 946, 1047, 1053, 1064, 1313, 1320, 1340
  • No cooling fan, no cooling water required, no noise and no vibration during laser operation, plug and play.
  • The diode-pumped Q-switched crystal lasers are based on our proprietary laser cavity technology. This new technology allows the Q-switched crystal lasers to operate in TEMoo mode with amplitude stability and extremely low power consumption in a ultra-compact housing.
  • If you need special configuration for the ultra-compact Q-switched pulsed laser, please contact CrystaLaser directly.
