Abstract:We report on the generation of highly stable active continuous

mode-locked pulses in diode pumped Nd:YVO4with an adjustable pulse

duration between34ps and1ns.With this laser an average output power of

up to7.3W with an excellent stability and beam quality with a M2-value

of<1.1is obtained.For all pulse durations the pulses were within a factor

of1.15above the Fourier limit.Due to these characteristics the presented

system is an attractive oscillator for OPCPA concepts.
