A high efficiency and high peak power picosecond (ps) mid-infrared optical parametric amplifier with a new nonlinear crystal pumped by a 30 ps 1064 nm Nd:YAG laser is demonstrated for the first time. The maximum photon conversion efficiency of 56% from 1064 nm to 3.9 μm idler has been achieved at the pump energy of . A maximum idler output of 830 μJ at 3.9 μm with peak power of was obtained at pump energy of . Moreover, a 3–5 μm idler tuning range was demonstrated, with output energies of at 5 μm and up to 1 mJ at 3 μm at pump energy.

We demonstrate a multiwavelength laser in the green-yellow region by means of a diode-pumped neodymium-doped yttrium aluminum garnet laser. This laser system combines a homemade 1074 nm and 1112 nm dual-wavelength laser with extracavity second harmonic generation (SHG) or sum-frequency generation in a lithium triborate crystal to generate visible output at any one of three wavelengths, 537 nm, 546 nm, and 556 nm, by simple temperature tuning, which has an important application in detecting carbon monoxide. The maximum average output power at the three wavelengths (537 nm, 546 nm, and 556 nm) was obtained to be 10.5 W, 0.5 W, and 8.5 W, respectively. The maximum SHG conversion efficiency from the infrared to the visible spectral region was about 51%.

A millijoule-level high pulse energy picosecond (ps) mid-infrared (MIR) optical parametric amplifier (OPA) at 3.9 μm based on large-aperture MgO-doped periodically poled lithium niobate (MgO:PPLN) crystal was demonstrated for the first time, to the best of our knowledge. The MIR OPA was pumped by a 30 ps 1064 nm Nd:YAG laser at 10 Hz and injected by an energy-adjustable near-infrared seed based on a barium boron oxide (BBO) optical parametric generator/optical parametric amplifier (OPG/OPA) with double-pass geometry. Output energy of 1.14 mJ at 3.9 μm has been obtained at pump energy of 15.2 mJ. Furthermore, the performance of MIR OPG in MgO:PPLN was also investigated for comparing with the seeded OPA.
