Abstract
A new diode-pumped solid-state multipass amplifier produced 38-dB small-signal gain at 1.047 μm in Nd:YLF with 1.6-W pump power and 37% extraction efficiency near saturation. The amplifier had a 1:1 confocally reimaging multipass design that generated both high gain and high efficiency. The same amplifier design with 13 W of pump power was tested with Nd:YAG at 1.064 μm, which gave 38-dB small-signal gain and 3.2 W of output power, and with Nd:YVO4, also at 1.064 μm, which gave >50-dB small-signal gain and 4.3 W of output power.Keywords
