Frequency Conversion Laser Head
First Claim
1. A laser assembly comprising a frequency conversion laser head operative to convert a portion of an input light propagating along a transmission light path at a fundamental frequency to a desired frequency of an output light, the frequency conversion laser head having a case, output and dump fibers partially housed in the case and guiding the converted portion at the desired frequency and an unconverted portion of the input light at the fundamental frequency, respectively, outside the case.

Abstract
A laser assembly is configured with a frequency conversion laser head operative to shift a fundamental frequency of input light to the desired frequency of an output light. The frequency conversion laser head includes a dump means operative to guide an unconverted output light at the fundamental frequency outside the case of the frequency conversion laser head. The dump means is configured with a guide optics operative to couple the output light at the fundamental frequency to a fiber terminating outside the case of the frequency conversion laser head.

20. A method for operating a laser head comprising:
-
coupling light at a fundamental frequency into a non-linear element operative to output light at desired and fundamental frequencies, respectively, which are different from one another; training the output light at a frequency selective element configured to transmit the output light at the desired frequency along a transmission path, and to reflect the output light at the fundamental frequency along a dump path extending transversely to the transmission path; coupling the transmitted light at the desired frequency into a one fiber located in a case of the laser head and the reflected light at the fundamental frequency into a dump fiber spaced from the one fiber within the case, thereby guiding the light at the desired and fundamental frequencies outside the case.
