1.3 W, super-octave-spanning Pulses at 2.3 μm from a Cr:ZnS Amplifier [PDF]

EPJ Web of Conferences
We investigate spectral broadening in TiO2 seeded by > 2 W, τ0.5 = 26 fs, 23 MHz pulses from a Cr:ZnS amplifier. We generate pulses covering spectrum from 1.1 to 3.2 µm at the -20-dB level at 1.3 W. © 2024 The Author(s)

Precise Measurement of Hyperfine Structure of Cesium 7S_1/2 Excited State

Applied Sciences, 2020
We present a precise measurement of the hyperfine structure of cesium 7 S 1 / 2 excited state by employing electromagnetically induced spectroscopy (EIS) with a cesium three-level cascade ( 6 S 1 / 2 − 6 P 3 / 2 − 7 S

Crossover from two-frequency pulse compounds to escaping solitons

Scientific Reports, 2021
The nonlinear interaction of copropagating optical solitons enables a large variety of intriguing bound-states of light. We here investigate the interaction dynamics of two initially superimposed fundamental solitons at distinctly different frequencies ...

Multi-Quartz Enhanced Photoacoustic Spectroscopy with Different Acoustic Microresonator Configurations

Journal of Spectroscopy, 2015
Acoustic microresonators were added to the recently developed multi-QTF based QEPAS spectrophone to enhance the signal amplitude. Two kinds of “on-beam” configurations were experimentally investigated in detail.

High power ultrafast phase-locked laser at 2060 nm from a doubly resonant optical parametric oscillator

Scientific Reports
A high-power 2- $$\mu$$ m phase-locked femtosecond source is demonstrated by a degenerate doubly resonant optical parametric oscillator (DROPO), which is synchronously pumped by a home-built Yb:YAG Kerr-lens mode-locked thin-disk laser.

Subjective nature of path information in quantum mechanics

Nature Communications
Common sense suggests that a particle must have a definite origin if its full path information is available. In quantum mechanics, the knowledge of path information is captured through the well-established duality relation between path distinguishability
