VESCENT PHOTONICS:
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 to 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 injection current tuned mode hop-free over more than 40 GHz, enabling very fast servo control for easy locking to atomic and molecular transitions. The D2-100 is a complete, ready-to-use 780nm laser diode module. It includes an anamorphic prism pair for beam Circularization and a 35dB optical isolator for clean, dependable mode hop-free operation.
