Abstract
A high-power single-frequency 1178 nm continuous-wave laser is generated in a two-stage stimulated-Brillouin-scattering-suppressed all-polarization-maintaining Raman fiber amplifier pumped by 1120 nm fiber lasers. A polarization-extinction-ratio of 30 dB is achieved due to the all-polarization-maintaining configuration and the polarization dependence gain of Raman scattering. Single-pass frequency doubling with a homemade periodically poled near-stoichiometric LiTaO(3) crystal (PPSLT) produces an up to 7 W narrow-linewidth laser at 589 nm. The thermally induced dephasing effect is found to be the key issue for improving second-harmonic efficiency.
