Abstract
A cryogenically cooled Yb:YLF laser with 224-W output power at 995 nm, linearly polarized along the c-axis, has been demonstrated, and laser oscillation has also been obtained polarized along the a-axis. The beam quality had an M2 ~ 1.1 at 60-W output and M² ~ 2.6 at 180-W output for c-axis polarization. This level of average power is approximately two orders of magnitude higher than demonstrated previously in cryogenic Yb:YLF. A cryogenic Yb:YLF mode-locked oscillator is under development, which will be used to as the input to a Yb:YLF amplifier to generate a short pulses at high average power.
