✦ Synopsis
We present a simple laser architecture to obtain continuous-wave (CW) true yellow light sources at the 579 nm. A 806 nm diode-pumped a Nd:YLF crystal emitting at 1047 nm with intracavity Raman shifting by SrWO 4 crystal at 1158 nm. Intracavity frequency-doubling at 1158 nm was then realized in a LiB3O5 (LBO) crystal to reach the yellow-orange radiation. To realize CW yellow radiation, high-Q resonator is applied to resonate two optical fields (i.e. the fundamental, and the first Stokes) by design high performance mirrors and partly sharing linear resonator. The stimulated Raman scattering (SRS) resonator losses is effectively reduced. We obtained a CW output power up to 889 mW at 579 nm with an incident pump power of 15.3 W at 806 nm, corresponding to an optical conversion efficiency of 5.8% with respect to the incident pump power LD 806 nm fiber-coupled diode laser Coupling lens Nd:YLF LBO SrWO 4 Output coupler 579 nm laser M2 M3 M1 1158 nm first Stokes resonator (M2-M3) 1047 nm fundamental resonator (M1-M3) Schematic of partly sharing linear resonator configuration for intracavity frequency-doubling of Nd:YLF/SrWO4/LBO Raman laser at 579 nm
