Compact fiber laser for 589 nm laser guide star generation

Abstract

In this paper, we developed an all-fiber laser system for generating a 589 nm source for laser-guided adaptive optics. The design is based on sum-frequency mixing two fiber lasers in a nonlinear material to produce a CW output at the desired wavelength. Combining an Er/Yb:doped fiber laser operating at 1583 nm with a 938 nm Nd:silica fiber laser, one can generate 589 nm via sum-frequency mixing in a periodically poled crystal. The integrated system design and performance is presented
