We report on a 888 nm diode-pumped Nd:YVO4 regenerative amplifier with up to 33.7 W output power with a repetition-rate of 20 kHz and an adjustable pulse duration between 217 ps and 1 ns. This setup allowed for efficient second harmonic generation with an efficiency of up to 79%.

We report on a passively mode-locked Nd:YVO4 self-Raman laser which consists of two coupled resonators and generates pulses at 1176nm with a duration of 4.8ps, a repetition rate of 73MHz, and an average power of 420mW.

Self-starting cw mode locking of a 888 nm pumped high-power Nd:YVO(4) laser using the χ(2):χ(2) cascaded Kerr lens in lithium triborate without exploiting the "nonlinear mirror" technique is presented. The nonlinear loss modulations are mainly provided by a soft aperture mechanism in the gain medium. A high average output power up to 15.4 W at 10.8 ps pulse duration and short pulses down to 5.7 ps at 11.4 W have been achieved.
