Over 100-kW peak power picosecond pulse generation at 2924 nm via efficient single-pass optical parametric generation with broadband tunability.

We report a high peak power mid-infrared (MIR) source via efficient optical parametric generation (OPG) in a piece of 50-mm-long MgO: PPLN crystal pumped by using a near-infrared (NIR) narrow-band picosecond laser source. The highest peak power of the idler pulse can reach ∼109.86 kW with a duration of ∼7.

Over 3.8 W, 3.4 µm picosecond mid-infrared parametric conversion based on a simplified one-to-many scheme.

In this paper, we demonstrate a simplified one-to-many scheme for efficient mid-infrared (MIR) parametric conversion. Such a scheme is based on a continuous wave (CW) single longitudinal mode master oscillator power-amplifier (MOPA) fiber system as the signal source and a picosecond pulsed MOPA fiber system, exhibiting multiple longitudinal modes, as the pump source. The signal and pump beams are combined and co-coupled into a piece of 50-mm long 5% MgO-doped PPLN crystal for the parametric conversion.
