Diode Pumped Infrared Laser

Ultra-compact High reliability High stability High efficiency

  • CrystaLaser, designs and manufactures state of the art ultra-compact diode-pumped Nd:YAG, Nd:YVO4 and Nd:YLF crystal lasers. Our infrared laser features with high stability, high efficiency, high reliability, low noise and excellent laser beam quality. These infrared lasers are specifically designed for laser trapping, laser tweezers, interferometer and OEM instrumentation, scientific research and industrial use.
  • Current available infrared laser products including ultra-compact diode-pumped CW Infrared laser and compact Q-switched Infrared laser systems.
  • New IR laser products:
    • Ultra-stable CW Infrared lasers, output stability 0.5% over 24 hours, are available now.
    • High power long coherence length, single longitudinal mode (SLM), TEMoo mode, narrow linewidth infrared laser systems at 1064 nm, 1053 nm, 1047 nm and other wavelengths available for injection seeding application.
    • Compact Q-switched infrared laser up to 2 W is available now.
    • Ultra-compact CW infrared laser up to 3 W is available as standard product.
    • Tunable infrared laser Q-switched Ti:Sapphire laser and CW Cr:LiSaF, Cr:LiCAF laser wavelength tunable from 780 to 980 nm
  • Many infrared laser wavelengths are available
    785, 808, 852, 980, 946, 1030, 1047, 1053, 1064, 1080, 1084, 1112, 1122, 1313, 1319, 1338, 1342, 1357, 1444, 1555 nm
  • The infrared lasers are easy to use, plug and play, no cooling fan, no cooling water required, no noise and no vibration during laser operation
  • The diode-pumped infrared lasers are based on our proprietary laser cavity technology. This laser technology allows our infrared lasers to operate in single longitudinal mode, TEMoo mode with low amplitude noise and extremely low power consumption in a compact laser housing.
