We demonstrate a continuous wave single-frequency laser at 671.1 nm based on a high-power 888 nm pumped Nd:YVO4 ring laser at 1342.2 nm. Unidirectional operation of the fundamental ring laser is achieved with the injection-locking technique. A Nd:YVO

A degenerate optical parametric oscillator (OPO) using an MgO:PPLN crystal and a volume Bragg grating (VBG) output coupler is presented. By changing the temperature of the VBG, the resonance of the OPO can be tuned exactly on the degeneracy point. A

We investigate the influence of the pump laser’s longitudinal mode structure on the spectral properties and stability of a narrowband Q-switched OPO near and on degeneracy (2128 nm) with a volume Bragg grating output coupler.

The generation of tunable mid-infrared picosecond laser radiation in the spectral range from 3–5µm by nonlinear frequency conversion in PPLN is reported. More than 3W output power at 3µm and 1.1W at 4.5µm were achieved.

We report on a high efficient kHz repetition rate ps OPG in LBO with an octave spanning tuning range. The total conversion efficiency exceeded 50% over a 950nm broad wavelength interval from 770nm to 1720nm.

We report on synchronously pumped OPOs with intracavity SHG or SFG in the same MgO:PPLN crystal. At e.g. 590 nm an output power of 190 mW was obtained with 140 fs pulses at a repetition rate of 81 MHz.
