✦ Synopsis

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:YVO 4 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 mode of operation was due to diode pump modulation and was used to reduce thermal stress of the crystal.

We report for the first time an efficient continuous wave (CW) laser emission at 561 nm by sum-frequency mixing of the fundamental and first-Stokes fields generated within an Nd:KGd(WO 4 ) 2 self-Raman laser. Intracavity sum-frequency mixing with LiB3O5 (LBO) nonlinear crystal yielded 570 mW of visi
