High Stability CW laser diode modules with laboratory style controller
Bluephoton® CWA Series – 375 nm – 488 nm
Greenphoton® CWA Series – 515 nm
Redphoton® CWA Series – 635 nm – 1060 nm
CWA–Laboratory-Style CW Lasers
The lasers of the CWA Series are highly-stable, temperature-stabilized diode lasers, with powers up to 500 mW and on request, modal jump-free CW operation. The high-precision temperature stabilization to a maximum diode temperature variation of <0.02°K and the stable power source for the laser diode, enable extreme power stability and very low noise levels.
The systems consist of a laser head and a laser controller in the 19” cassette housing, with integrated 90-240 V AC 50/60 Hz power unit for global employment. The integrated modulation inputs for analog power modulation with up to 1kHz, and TTL modulation with up to 10k Hz, enable integration into control and measurement processes. As in case of all lasers of the Bluephoton® and Redphoton® Series, the laser head can be very simply adapted to customer specifications by the use of the modular principle
