We present a compact high-efficiency and high-average-power diode-side-pumped Nd:YAG rod laser oscillator operated with a linearly polarized fundamental mode. The oscillator resonator is based on an L-shaped convex–convex cavity with an improved module and a dual-rod configuration for birefringence compensation. Under a pump power of 344 W , a linearly polarized average output power of 101.4 W at 1064 nm is obtained, which corresponds to an optical-to-optical conversion efficiency of 29.4%. The laser is operated at a repetition rate of 400 Hz with a beam quality factor of M 2 = 1.14 . To the best of our knowledge, this is the highest optical-to-optical efficiency for a side-pumped TEM 00 Nd:YAG rod laser oscillator with a 100-W-level output ever reported.
