Multiple-color cw visible lasers by frequency sum-mixing in a cascading Raman fiber laser

Multiple-color cw visible lasers by frequency sum-mixing in a cascading Raman fiber laser

Yan Feng, Shenghong Huang, Akira Shirakawa, and Ken-ichi Ueda, University of Electro-Communications

Multiple cw visible lasers at wavelengths ranging from 550nm to 625nm were generated by intracavity frequency sum-mixing of a cascading Raman fiber laser in a type-I noncritically phase-matched lithium triborate crystal. The phase matching conditions for individual wavelengths were realized by tuning the temperature of the lithium triborate crystal.
