Laser action is demonstrated in Yb:KYW at wavelengths of 990 nm, 997 nm and 1066 nm, when pumped at 980 nm by a Ti:sapphire laser, with a lowest laser quantum defect of 1.0%. The laser output powers at the various wavelengths were 70mW, 160mW and 140mW, respectively. Locking of the laser wavelength and the spectrally close spacing of pump and laser were achieved by the use of a volume Bragg grating as an input coupler. A theoretical model is also presented that accurately describes the laser at various wavelengths, by solving the laser rate equations at spatial points throughout the laser crystal.
