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 …

Tailoring the electric-field waveform of ultrashort light pulses forms the basis for controlling
nonlinear optical phenomena on their genuine, attosecond timescale. Here we extend …

Using sub-3-cycle pulses from mode-locked Cr: ZnS lasers at λ≈ 2.4 µm as a driving
source, we performed high-resolution dual-frequency-comb spectroscopy in the longwave …

A sub-picosecond mid-infrared laser based on hollow-core silica fiber is demonstrated for
the first time. By using deuterium-filled revolver fiber as an active medium, we realized …

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 …

Ultrabroadband electro-optic sampling using few-optical-cycle probing pulses is a sensitive
technique to detect electric field amplitudes with a high dynamic range and up to near …

We report, to the best of our knowledge, the first super-octave femtosecond polycrystalline
Cr: ZnS laser at the central wavelength 2.4 µm. The laser is based on a non-polarizing …

The chromium ion is among the most widely explored and used laser-active ions.
Depending on the charge state of the laser-active chromium ion in the host, tunable …

Single-cycle optical pulses with controllable carrier-envelope phase (CEP) form the basis to
manipulate the nonlinear polarization of matter on a sub-femtosecond time scale. Moreover …

Supercontinuum sources based on intrapulse difference frequency generation (IDFG) from
mode-locked lasers open new opportunities in mid-infrared gas spectroscopy. These …
