Red Laser, DPSS red laser system and red laser module
Red Laser
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.
Current available red laser products including CW red laser and Q-switched red laser products.
New red laser products:
- 633 nm single longitudinal mode red laser available up to 50 mW is suitable for red He-Ne laser replacement
- Red laser 638 nm and 642 nm single longitudinal mode laser available up to 70 mW
- 300mW, 640 nm TEMoo mode red laser available
- 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
- Long coherence length single longitudinal mode red crystal lasers with output power up to 50 mW at 633nm and 640nm, 250 mW at 671 nm, 100 mW at 660 nm and 780.2nm are available. The single longitudinal mode red lasers feature narrow linewidth, wavelength stable, 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.
