Mid-infrared (MIR) nonlinear optical (NLO) crystals are commonly used as the core devices
for all-solid-state MIR lasers which play a key role in many military and civilian areas. The …

The advent of chirped-pulse amplification in the 1980s and femtosecond Ti: sapphire lasers
in the 1990s enabled transformative advances in intense laser–matter interaction physics …

We demonstrate how a scheme called advanced dual-chirped optical parametric
amplification (DC-OPA) that employs two kinds of nonlinear crystal (BiB3O6 and MgO-doped …

Nonlinear vibrational spectroscopy profits from broadband sources emitting in the molecular
fingerprint region. Yet, broadband lasers operating at wavelengths above 7 μm have been …

12 μm 长波红外波段激光位于大气传输窗口并覆盖诸多气体分子的吸收带, 在大气探测,
光电对抗等领域具有重要的应用. 目前, 通过粒子数反转激光器直接辐射以及非线性频率变换 …

Single-cycle pulses with a deterministic carrier-envelope phase enable the study and control
of light–matter interactions at the sub-cycle timescale, as well as the efficient generation of …

We report the single-cycle optical control of a freely propagating electron beam with an
isolated cycle of midinfrared light. In particular, we produce and characterize a modulated …

In high fluence applications of lead halide perovskites for light-emitting diodes and lasers,
multi-polaron interactions and associated Auger recombination limit the device performance …

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 …
