Ultra-compact  High reliability  High stability  High efficiency

  • CrystaLaser, designs and manufactures state of the art ultra-compact red laser systems. Our red laser features with high stability, high efficiency, high reliability, low noise and excellent laser beam quality. These red lasers are specifically designed for OEM, scientific and industrial use.
  • Red laser Type 4
  • Current available red laser products including CW red laser and Q-switched red laser products.
  • New red laser products:
    • Red laser, 633 nm single longitudinal mode laser available up to 35 mW is suitable for red He-Ne laser replacement
    • Red laser, 638 nm single longitudinal mode laser available up to 70 mW
    • Red laser, 642 nm single longitudinal mode laser available up to 100 mW
    • Red laser with fast TTL modulation up to 200 MHz option is available for the wavelength range from red 635 nm up to near infrared 1550 nm
    • High power red crystal lasers with diffraction limited single mode beam output are available now. The red laser output power is up to 350 mW at 671 nm and 300 mW at 656 nm and 660 nm
    • High power long coherence length single longitudinal mode red crystal lasers with output power up to 250 mW at 671 nm and 25 mW at 656 nm are available. The single longitudinal mode red lasers feature narrow linewidth, wavelength tunable, and with long coherence length of >300 meters. The lasers are suitable for holography, interferometer, for magnet-optical trapping of lithium atoms and Raman spectrum applications
    • Diode-pumped Q-switched red crystal lasers are available at 656nm, 660 nm and 671 nm.
  • Wavelengths of the red lasers and near infrared lasers:
    633 nm, 638 nm, 642 nm, 647 nm, 655 nm, 656.5 nm, 660 nm, 671 nm, 690 nm, 780 nm, 785 nm, 808 nm, 852 nm, 980 nm, 1310 nm, 1550 nm and more.
  • The red laser is easy to use, plug and play, no cooling fan, no cooling water required, no noise and no vibration during laser operation
  • The red lasers are based on our proprietary laser design technology. This laser technology allows our red lasers to operate in TEMoo mode with long coherence length and extremely low power consumption in a compact laser housing.
  • If you need special requirements or configurations of the red laser, please contact CrystaLaser.
