A 1.35 μm laser diode pumped continuous wave KGW:Nd laser

Abstract A 1.35 μm continuous-wave laser operation in potassium gadolinium tungstate (KGd(WO 4 ) 2 :Nd 3+ or KGW:Nd) under laser diode end-pumping have been achieved. The effects of wavelength variations of the pump source on the stability of the solid-state laser output power and efficiency have been investigated. Second harmonic generation has been obtained for an intracavity configuration.
