✦ Synopsis

A diode-pumped actively Q-switched and modelocked Nd:GdVO4 laser with great average output power and high efficiency was realized by using a comparative simple configuration and a short cavity length. The laser generates stable mode-locked pulses of estimated width 240 ps lying underneath a Q-switched envelope of width 170 ns with a Q-switch modulation frequency of 10 kHz. The modulation depth was more than 90% and the mode-locked pulse inside the Q-switched pulse has a repetition rate of 390 MHz. T Ch1 20.0mV M ACh1 68.0mV 100ns

Oscilloscope traces of a typical actively Q-switched and modelocked laser pulse envelope at the incident pump power of 2.1 W and the pulse repetition of 10 kHz
