Inherent laws between tetrahedral arrangement pattern and optical performance in tetrahedron-based mid-infrared nonlinear optical materials

W Wang, D Mei, F Liang, J Zhao, Y Wu, Z Lin - Coordination Chemistry …, 2020 - Elsevier
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 …

Octave-spanning single-cycle middle-infrared generation through optical parametric amplification in LiGaS2

BH Chen, E Wittmann, Y Morimoto, P Baum… - Optics …, 2019 - opg.optica.org
We report the generation of extremely broadband and inherently phase-locked mid-infrared
pulses covering the 5 to 11 µm region. The concept is based on two stages of optical …

Broadly tunable mid-infrared femtosecond pulses directly generated by an optical parametric amplifier

A Villa, AM Ross, R Gotti, M Lamperti… - OSA …, 2021 - opg.optica.org
We introduce an optical parametric amplifier, pumped by an amplified femtosecond Yb:
KGW laser, which directly generates broadly tunable mid-infrared (MIR) pulses, covering the …

Compression of picosecond pulses from a thin-disk laser to 30fs at 4W average power

BH Chen, M Kretschmar, D Ehberger, A Blumenstein… - Optics express, 2018 - opg.optica.org
We investigate two approaches for the spectral broadening and compression of 1-ps long
pulses of a thin-disk laser amplifier running at 50 kHz repetition rate at 1030 nm wavelength …

Second-harmonic generation and self-phase modulation of few-cycle mid-infrared pulses

BH Chen, C Hofer, I Pupeza, P Baum - Optics Letters, 2019 - opg.optica.org
Near-single-cycle mid-infrared pulses with a spectrum covering 5.4–11 μm are efficiently
frequency-doubled in different GaSe crystals. The second-harmonic spectrum spans 3–4.3 …

[PDF][PDF] Single-cycle mid-infrared pulse generation via nonlinear optics

BH Chen - 2019 - pure.mpg.de
Physical and chemical processes that involve electronic or molecular dynamics pretty much
establish the world we perceive every day. These ultrafast motions can be either indirectly …
