Externally pumped yellow laser source emitting at 577 nm

Abstract

Abstract We demonstrated a 577 nm yellow laser source with a proper combination of Raman medium and frequency doubling medium, pumped externally. Cryogenic Yb:YAG oscillator acts as an external pump source, and it generates 1.2 mJ energy at 1 KHz emitting around 1029 nm. Using a Raman resonator with Ba(NO3)2 as Raman medium, stimulated Raman scattering around 1153.4 was generated. Finally, 577 nm yellow laser was generated using the frequency-doubling medium LBO. A maximum average output power of 65 mW with a pulse duration of 18 ns at 1 KHz was achieved.
