The output characteristics of 579 nm high power resonator KGd(WO4)2 Raman yellow laser were reported. 579.54 nm yellow laser was generated based on 808nm pulse LD sidepumped ceramic Nd∶YAG, BBO electrooptical Qswitched and typeI critical phasematching LBO crystal extracavity frequency doubling project. With the 5.02 W, 10.1 ns and 1 kHz output power pumped at 532 nm, the laser produced high average power of 2.58 W and pulses of 7.4 ns duration secondStokes wavelength at 579.54 nm. Conversion efficiency was 51.4% and slope efficiency was 54.8%. The beam quality factors M2 of 579.54 nm were M2x－579.54=5.829, M2y－579.54=6.336 and power instability less than ±2.35%. Experimental results indicate that external resonator Raman structure is an effective method for obtaining Raman yellow laser with its high opticaltooptical conversion and good power stability. Moreover, the additional usage of pulse LD with synchronous electrooptical Qswitch could generate high repetition rate, high average power, narrow pulse width and high peak power yellow laser.
