✦ Synopsis

We have achieved high average power Raman output from a compact, diode-pumped, self-stimulating Nd 3+ :KGd(WO 4 ) 2 Raman laser. Maximum Raman output power of 0.8 W was achieved at a pulse repetition frequency (PRF) of 2 kHz. The optical efficiency from diode to Raman laser was 14%. By generating extra-cavity second harmonics using a LiB 3 O 5 crystal, it was possible to produce 0.2 W yellow output. The laser system was simulated numerically using rate equations and the results obtained were in good agreement with the experimental results.
