We describe efficient cw operation of a Nd:YLF laser end pumped by two beam-shaped 20-W diode bars on the 1.053-µm transition. Fundamental transverse-mode operation with output power of 11.1 W for ∼29.5 W of incident pump power was demonstrated. In Q-switched operation 8.4 W of average power at a pulse repetition frequency of 40 kHz and ∼2.6-mJ pulse energy at a pulse repetition frequency of 1 kHz were achieved.
