 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.
