Red Laser Module

Ultra-compact High efficiency High reliability Low noise

CrystaLaser designs and manufactures cost effective ultra-compact red laser module and red laser systems. Our red lasers feature with high stability, high efficiency, high reliability, low noise and excellent laser beam quality. These red lasers are specificly designed for OEM, scientific and industrial use.

Diode-pumped Q-switched red crystal lasers are available at 656nm, 660 nm and 671 nm.

New! Single longitudinal mode red laser module up to 50 mW with long coherence length of >50 meters is available. The single longitudinal mode red laser is suitable for hologhaphy, interferometer and Raman spectrum applications

The laser laser module is easy to use, plug and play, no cooling fan, no cooling water required, no noise and no vibration during laser operation

New red laser products:

Red laser with fast TTL modulation up to 200 MHz option is available for the wavelength range from red 635 nm up to near infra-red 1550 nm
High power red lasers with diffraction limited single mode beam output are available now. The red laser output power is up to 300 mW at 671 nm and 300 mW at 656 nm and 660 nm
High power long coherence length single longitudinal mode red lasers with output power up to 250 mW at 671 nm and 25 mW at 656 nm are available. The single longitudinal mode red laser features narrow linewidth, wavelength tunable, and with long coherence length of >300 meters. The red laser is suitable for holography, interferometer, for magneto-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 laser module and near infra-red laser modules:
635 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 modules are based on our proprietary laser design technology. This new 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.
