Quasi continuous‐wave (qCW) yellow emission (pulse duration 5 ms, repetition rate 20 Hz) at 559 nm is demonstrated through intracavity sum frequency generation (SFG) of Stokes and fundamental fields in Nd:YVO4 diode pumped self‐Raman laser for the first time. Average in pulse output power at 559 nm was 0.47 W for 22 W of pump power, which corresponds to 2.1% of diode‐to‐yellow efficiency. The pulsed...
Stimulated Raman scattering (SRS) is a traditional method for laser frequency conversion. Last time much attention is paid to Raman conversion in crystal mediums, because it opens new perspectives for development of solid-state laser systems. Raman conversion of femtosecond pulses faces difficulties connected with transient conditions and competition with other nonlinear effects. This work presents...
