Abstract
CAVITY: We present what is, to our best knowledge, the first Yb:KY(WO4); (Yb:KYW) regenerative amplifier. The schematic diagram is shown in figure 1. The 10-at.% Yb3+-doped KY(WO4)2 crystal is 4-mm long and cut at Brewster angle for the E/b signal beam. A water-cooled copper mount allows the Yb:KYW to be cooled through both top and bottom faces to 18°C.The crystal is cw end-pumped by two 1.6-W, 100-µm stripe laser diodes operating at 940 nm with a spectral bandwidth of-3 nm FWHM
