Green Laser  Ultra-compact  High reliability  High stability  High efficiency

  • CrystaLaser designs and manufactures state of the art ultra-compact diode-pumped green laser systems. Our green lasers feature with high reliability, high stability, high efficiency, low noise and excellent laser beam quality.
  • The diode-pumped solid-state DPSS crystal green laser products including DPSS CW green laser and DPSS Q-switched green laser systems. The SHG of Nd:YAG, Nd:YLF, Nd:YVO4 green lasers with true CW output and Q-switched pulsed output are for industrial instrumentation applications in holography, biomedical, fluorescence, reprographics, laser trapping, laser Raman, interferometry, semiconductor inspection and materials processing.
  • New green laser products:Diode pumped green YAG Laser
    • 532 nm green laser outputs 1W in a compact laser housing with low power consumption.
    • 100 mW yellowish green laser at 542 nm; up to 250 mW greenish yellow laser at 561 nm and 555 nm.
    • Ultra-stable CW green laser, output stability 0.55 and 0.25% over 24 hours, is available now.
    • Compact Q-switched Green Lasers at 532 nm, 523 nm, 527 nm, 542 nm, 555 nm and 561 nm are available now.
    • Up to 250 mW, single longitudinal mode, 532 nm green laser with more than 300 meters coherence length is suitable for holography and interferometry applications.
  • The green laser is easy to use, plug and play, no cooling fan, no cooling water required, no noise and no vibration during laser operation.
  • The diode-pumped green lasers are based on our proprietary coupled-cavity laser technology. This patented laser technology allows our green lasers to operate in a single longitudinal mode and TEMoo mode with low noise and extremely low power consumption in a compact laser housing.
  • If you need special configurations of green lasers, other special wavelength of the green laser or higher power green laser up to 5 W, please contact CrystaLaser directly.
  • Wavelengths of the green lasers: 532 nm, 523 nm, 527 nm, 542 nm, 555 nm, 558 nm and 561 nm. Please download the specifications of
