Patent ID: 8179934

Claim:
A laser assembly comprising a frequency conversion laser head receiving at a fundamental frequency, and comprising: a case; a non-linear conversion component housed in the case and operative to convert a portion of the light to a desired frequency; a beam splitter mounted in the case and configured to transmit the converted light portion along a transmission path and reflect an unconverted portion of the light at the fundamental frequency along a light dump path; an output fiber located along the transmission path and receiving the converted light portion at the desired frequency; and a dump fiber partially housed in the case along the dump path and configured to receive and launch the unconverted light portion at the fundamental frequency outside the case; a mirror located downstream from the beam splitter along the dump light path and configured to reflect the light at the fundamental frequency towards the dump fiber; and a dump focusing optics downstream from the mirror and operative to couple the output light at the fundamental frequency into the dump fiber.
