      Green Laser Module

      Ultra-compact  High reliability  Low noise  Low cost

      • CrystaLaser designs and manufactures cost effective ultra-compact diode-pumped green crystal lasers. Our green lasers feature with high reliability, high stability, high efficiency, low noise and excellent laser beam quality. These lasers are specificly designed for OEMs, scientific and industrial use.
      • CrystaLaser manufactures compact diode-pumped solid-state DPSS green crystal laser products including diode-pumped 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, semiconduct inspection and materials processing.
          Ultra-stable CW green laser, output stability 0.25% over 24 hours, is availible now.
          Compact Q-switched UV, Green, and IR lasers are availible now.
          Up to 200 mW, single longitudinal mode, 532 nm green laser with more than 100 meters coherence length is suitable for holography and interferometry applications.
      • Wavelengths of the green lasers: 532 nm, 523 nm and 527 nm.
      • 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 crystal lasers are based on our proprietary coupled-cavity laser technology. This patented laser technology allows our green and infrared crystal lasers to operate in a single longitudinal mode and TEMoo mode with low amplitude noise and extremely low power consumption in a compact housing.
      • If you need special configurations of green lasers, 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
