D2-100 DBR Laser

The D2-100-DBR laser module is comprised of a distributed Bragg reflector (DBR) laser diode in a precision temperature-controlled housing with beam conditioning optics and an optical isolator. DBR laser diodes are fabricated with the feedback grating patterned directly adjacent the gain section of the diode. They are highly immune to vibrations and by virtue of a very short cavity (~ 1 mm), they can be current tuned over more than 40 GHz. The result is a robust laser capable of very fast servo control for easy locking to atomic and molecular transitions. The module contains no moving parts or piezo-electrics and is therefore inherently robust and rugged. Furthermore, DBR lasers have 2-3 times larger temperature and current tuning coefficients as compared to external-cavity diode lasers. In the D2-100 these parameters may be accurately controlled with two stages of temperature control and a precision low-noise current controller with fast servo input. The DBR laser is collimated by a 0.55 NA lens mounted to a movable plate for pointing adjustments. The module also comes with a 35 dB optical isolator and a pair of anamorphic prisms.
