We report a long-wavelength mid-infrared (mid-IR), few-cycle optical parametric chirped-
pulse amplifier (OPCPA) based on LiGaS_2 crystals, pumped by a 1 μm Yb: YAG laser, at a …

We report on an optical architecture delivering sub-120 femtosecond laser pulses of 20 µJ
tunable from 5.5 µm to 13 µm in the mid-infrared range (mid-IR). The system is based on a …

We demonstrate the first (to the best of our knowledge) tunable femtosecond (fs) mid-
infrared (MIR) optical parametric amplifier (OPA) based on BaGa_4Se_7 (BGSe) crystal with …

We present a setup for generating broadband (up to 1050 cm^− 1) and broadly tunable (2.5-
15 µm) mid-infrared pulses using an Yb-doped femtosecond laser as the pump source. Our …

We report optical parametric amplification (OPA) of low-frequency infrared pulses in the
intermediate region between terahertz (THz) frequency and mid-infrared (MIR), ie, from 16.9 …
