View article: Spatial phase coherence in femtosecond coherent Raman scattering
Spatial phase coherence in femtosecond coherent Raman scattering Open
Conventional femtosecond coherent laser spectroscopy predominantly focuses on the temporal phase coherence through time- or frequency-resolved methods. In this work, we suggest an alternative experimental framework based on spatial phase c…

Fine-structure rotational coherent anti-Stokes Raman scattering in iron vapor Open
Spontaneous and coherent Raman scattering can be used to perform atomic spectroscopy by probing the fine structure of the target atom's electronic configuration arising from spin-orbit coupling. We report, to our knowledge, the first appli…

Spatial characterization of sideways lasing Open
Strong excitation with high electromagnetic fields can generate lasing in gaseous media by resonant excitation. Previous efforts have shown that the lasing signal can be emitted perpendicular to the direction of the pump laser if the shape…

Exploring Time‐Domain Femtosecond Rotational Coherent Raman Scattering for Diagnostics Open
The diagnostic potential of femtosecond (fs) rotational coherent Raman scattering (RCRS) in the time domain is initially investigated. While RCRS concepts in the spectral domain obtain species selectivity and temperature sensitivity by res…

Interferometric quantum control (IQC) by fs/ns rotational coherent anti-Stokes Raman spectroscopy (RCARS) Open
A new rotational coherent anti-Stokes Raman spectroscopy (RCARS) concept based on interferometric quantum control (IQC) is demonstrated. Two wavepackets originating from pure rotational states are created by a femtosecond stimulated rotati…

Single-shot coherent control of molecular rotation by fs/ns rotational coherent anti-Stokes Raman spectroscopy Open
We present a novel method, to our knowledge, to control the shape of the spectra using 2-beam hybrid femtosecond (fs)/nanosecond (ns) coherent anti-Stokes Raman scattering (RCARS). The method is demonstrated experimentally and theoreticall…

Laser-induced thermal grating spectroscopy based on femtosecond laser multi-photon absorption Open
Laser-induced grating spectroscopy (LIGS) is for the first time explored in a configuration based on the crossing of two focused femtosecond (fs) laser pulses (800-nm wavelength) and a focused continuous-wave (cw) laser beam (532-nm wavele…

Investigating the pathogenicity of Alternaria alternata on Lonicera japonica Open
This study was carried out to investigate the pathogenicity of Alternaria alternata and the effect of its metabolites on L. japonica from 2015- 2016 in Birjand plain area in eastern Iran. A. alternata isolates were inoculated on L. japonic…

Diode laser-based thermometry using two-line atomic fluorescence of indium and gallium Open
A robust and relatively compact calibration-free thermometric technique using diode lasers two-line atomic fluorescence (TLAF) for reactive flows at atmospheric pressures is investigated. TLAF temperature measurements were conducted using …
