Abstract:
A laser diode detector assembly, comprising:an enclosure defining a volume therein;a plurality of elements disposed in the volume, including:a laser diode which produces an optical output out of a front side of said laser diode, andat least one input end of at least one optical fiber disposed adjacent said front side of said laser diode to optically couple said optical output into said optical fiber, the optical fiber traversing out of said enclosure, wherein a portion of said optical output is not coupled into said optical fiber and is directed out into said volume as stray light which undergoes multiple reflections off of internal surfaces of said enclosure and said plurality of elements therein for integrating the stray light; anda detector positioned to detect at least a portion of said integrated stray light only after said stray light has undergone at least one of said reflections.
