Over 20-W Mid-Infrared Picosecond Optical Parametric Oscillator

IEEE Photonics Journal, 2015
We report on a high-average-power mid-infrared picosecond optical parametric oscillator (OPO) synchronously pumped by a Nd:YVO4 mode-locked laser. By use of the MgO-doped periodically poled LiNbO3 as the nonlinear crystal, up to 20.2-W picosecond laser ...

Wavelength-Tunable Nonlinear Mirror Mode-Locked Laser Based on MgO-Doped Lithium Niobate

Crystals, 2020
We present a high-power, wavelength-tunable picosecond Yb3+: CaGdAlO4 (Yb:CALGO) laser based on MgO-doped lithium niobate (MgO:LN) nonlinear mirror mode locking. The output wavelength in the continuous wave (CW) regime is tunable over a 45 nm broad range.
