Abstract

The ongoing advancement of Ti:sapphire femtosecond laser technology has drawn increasing attention to high repetition rate, high-energy green lasers as ideal pump sources for Ti:sapphire regenerative amplifiers. This study employed a neodymium-doped yttrium lithium fluoride (Nd:YLF) as the gain medium, supplemented with side-pumped laser diodes, acousto-optic $Q$-switching, and intracavity frequency doubling technologies. The results demonstrated a repetition rate ranging from 1–10 kHz, a pulse width of less than 100 ns, and a single pulse energy exceeding 50 mJ at 527 nm green light output. Furthermore, an operating stability (RMS) of ${\le} {0.15}\%$ was maintained for 14 h at a repetition rate of 1 kHz and an output power of 40 W.
