Abstract By using a diode-side-pumped Q-switched Nd:YAG rod laser based on a thermally-near-unstable flat--flat resonator, an intracavity-frequency-doubled green beam generation is investigated. Output power 140W is obtained at a repetition rate of 10kHz and a pulse width of 110ns. The green beam quality factors M²_x and M²_y, which are measured by a laser beam analyser, are 10.65 and 10.85, respectively, at output power of 124W.
