The development of parametric devices down-converting the laser frequency to the mid-
infrared (3–30 µm) based on non-oxide nonlinear optical crystals is reviewed. Such devices …

Recent developments in laser sources operating in the mid-IR (3–8 μ m) have been
motivated by the numerous possibilities for both fundamental and applied research. One …

We report on the parametric generation of 100 fs sub-6-cycle 40 μJ pulses with the center
wavelength at 5.2 μm using a 1 ps 2.1 μm pump laser and a dispersion management …

When coupled to characteristic, fingerprint vibrational and rotational motions of molecules,
an electromagnetic field with an appropriate frequency and waveform offers a highly …

Dual-comb spectroscopy has been proven beneficial in molecular characterization but
remains challenging in the mid-infrared region due to difficulties in sources and efficient …

We have developed a robust optical parametric amplifier (OPA) based on three-AgGaS_2-
crystal pumping by a Cr: Forsterite GW femtosecond laser system, generating 150 fs pulses …

A physical scenario whereby freely propagating mid-infrared pulses can be compressed to
pulse widths close to the field cycle is identified. Generation of tunable few-cycle pulses in …

Carrier-envelope-phase (CEP) controlled subcycle midinfrared pulses generated through
two-color filamentation have been applied for high-harmonic (HH) generation in a crystalline …

This paper summarizes the generation of sub-single-cycle infrared (IR) pulses through a
laser filament and the detailed properties of the generated pulses. The fundamental (ω 1) …

Traditional absorption spectroscopy has a fundamental difficulty in resolving small
absorbance from a strong background due to the instability of laser sources. Existing …
