A 1.35 mu m continuous-wave laser operation in potassium gadolinium tu
ngstate (KG(WO4)(2):Nd3+ or KGW:Nd) under laser diode end-pumping have
been achieved. The effects of wavelength variations of the pump sourc
e on the stability of the solid-state laser output power and efficienc
y have been investigated. Second harmonic generation has been obtained
for an intracavity configuration. (C) 1998 Elsevier Science B.V. All
