High-harmonic spectroscopy, an ultrafast all-optical technique initially conceptualized in
atomic and molecular systems, has now emerged as a powerful platform for studying the …

This article provides an overview of laser-based absorption spectroscopy applications and
discusses the parameter space and requirements of laser systems for each of these …

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 …

A femtosecond chirped pulse amplifier based on cryogenically cooled Fe: ZnSe was
demonstrated at 333 Hz—33 times higher than previous results achieved at near-room …

We report a coherent layer-by-layer build-up of high-order harmonic generation (HHG) in
artificially stacked transition metal dichalcogenides (TMDC) crystals in their various stacking …

Pneumatic soft robot attracts extensive attention because of its own characteristics. It has
great application potential in medical and other fields. Although the recent improvement of …

We demonstrate what we believe to be a new approach to energetic picosecond 10.2-µm
pulse generation based on nonlinear mixing of subnanosecond single-frequency 1338-nm …

Optical rectification (OR) is a popular way to generate coherent terahertz radiation. Here, we
develop a sub-picosecond mid-infrared (mid-IR) light source with a tailored wavelength and …

Few-cycle pulses were generated by passing a beam from a cryogenically cooled Fe: ZnSe
chirped-pulse amplifier (CPA) at a repetition rate of 400 Hz through a gas-filled hollow core …

We present a compact nonlinear compression scheme for the generation of millijoule few-
cycle pulses beyond 4 µm wavelength. For this purpose 95? fs pulses at 5 µm from a 1? kHz …
