589 nm Light Source Based on Raman Fiber Laser

Abstract

A fiber-based continuous-wave laser at 589 nm was demonstrated by intracavity frequency doubling of a Raman fiber laser at 1178 nm in a type-I noncritically phase matched lithium triborate crystal. The yellow laser output was limited by the emergence of higher order Stokes Raman emission and the broad linewidth of the fundamental laser at 1178 nm.
