 The DBR laser module is comprised of a distributed feedback (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 over 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 50 GHz.  The result is a robust laser capable of very fast servo control for easy locking to atomic transitions. ​ The module contains no moving parts or piezo-electrics and is therefore inherently robust and rugged. The DBR laser module is comprised of a distributed feedback (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 over 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 50 GHz.  The result is a robust laser capable of very fast servo control for easy locking to atomic transitions. ​ The module contains no moving parts or piezo-electrics and is therefore inherently robust and rugged.
