We demonstrate a new management of multi-stage optical parametric generator (OPG) and amplifier (OPA) to obtain high-energy picosecond sources with high beam quality. The setup of multi-stage OPG-OPA requires mode-matching between the pump beam and the stable mode of the OPG-OPA. In a proof-of-principle experiment, the single-pass multi-stage OPG-OPA consists of three walk-off compensated KTP crystal pairs and two lenses, pumped by an 86 ps, 1064 nm 10 kHz picosecond laser. The signal light at ∼ 1.77 μ m has an average output power of 502 mW with record energy up to 50.2 μ J. The beam quality factor of the signal light can be improved to M x 2 × M y 2 = 1.87 × 2.16 after filtering out about 40% signal power. To the best of our knowledge, it is the first picosecond single-pass multi-stage OPG-OPA pumped at kHz regime.

“…Therefore, PPLN-OPO has become one of the research hotspots in recent years. Mei et al 6 designed a PPLN intracavity optical parametric oscillator pumped by a diode-end-pumped Nd∶YVO 4 laser with a maximum output power of 3.41 W, corresponding to the conservation efficiency of 18.5% at the central wavelength of 2 μm. Parsa et al 7 reported a Yb-fiber-pumped picosecond PPLN-OPO that can provide a 1561-nm signal beam with the power of 4 W and maximum extracted efficiency of 45.5%.…”

A high conservation efficiency periodically poled LiNbO 3 (PPLN) optical parametric oscillator (OPO) based on the plano-convex unstable resonant cavity is demonstrated. The OPO is pumped by a Q-switch quasi-continuous-wave Nd∶YVO 4 with a wavelength of 1064 nm. The thermal effect of the nonlinear crystal and the mode distribution under the plano-convex cavity are analyzed. Through temperature tuning, the wavelength of the signal laser covers 1471.4 to 1510.4 nm. When the temperature is 30°C, the repetition rate is 30 kHz, and the pump power is 5.7 W. A PPLN-OPO based on a plano-convex cavity generates a 1471.4-nm laser with a maximum output power of 1.09 W and pulse duration of 17.14 ns. The highest pump-to-signal conversion efficiency is 28.71%. When the repetition rate is 40 kHz, the highest conversion efficiency of 29.29% is achieved at the pump power of 2.8 W.
