title: High power 2 MHz passively Q-switched nanosecond Nd:YVO4/Cr4+:YAG 914 nm laser.
abstract: We report a high-power, high-repetition-rate end-pumped passively Q-switched Nd:YVO4/Cr4+: yttrium aluminum garnet 914 nm laser. The maximum output power of 3.8 W at 914 nm is achieved at 2 MHz with the absorbed pump power of 25.2 W. The highest single pulse energy of a pulsed 914 nm laser reaches 2.3 μJ with a pulse width of 27.1 ns.
