Diode-laser-pumped Nd:YLF lasers are demonstrated at 1.047 µm with less than 1-mW thresholds and internal quantum efficiencies approaching 70%. Operation at 1.053 µm has also been achieved. Intracavity second harmonic generation using MgO:LiNbO3 has generated up to 145-µW output at 523.6 nm for 30.1 mW of diode-laser pump power.
