Abstract

We demonstrate a diode-pumped Yb:KYW laser, where the wavelength is controlled by a transversely chirped volume-Bragg-grating, also used as the laser output coupler. By translating the grating, the wavelength could be tuned from 997 nm to 1016 nm, with a spectral bandwidth of 13 GHz and a power up to 3.3 W. The laser cavity is simple and compact, and the tuning method is generally applicable to many other laser systems.
