Abstract
The room-temperature Yb:YAG laser at 1.03 μm has the potential for high-power single-spatial-mode operation because of its broad absorption bandwidth (making control of the pump wavelength less important), the absence of mechanisms other than radiative relaxation to deplete the upper state, and the low thermal loading as a result of the small quantum defect.1 The lasing transition has a 60-cm−1 width, which may allow mode-locking to give pulses as short as 0.2 ps. We present initial results on mode-locking of the laser and on optimization of the laser cavity to obtain 1.56 W of laser output.
