Diode-Pumped High-Power cw Nd:YAG Lasers

Diode laser side-pumped, cw Nd:YAG rod lasers operating at pump powers up to 1.1 kW will be reported on. In multimode operation at 1064 nm, output powers of more than 300 W cw are observed. Higher pump powers up to several 100 W/cm can be achieved by using fiber-coupled diode lasers as pump sources.
