Competing Inversion-Based Lasing and Raman Lasing in Doped Silicon

Physical Review X, 2018
We report on an optically pumped laser where photons are simultaneously generated by population inversion and by stimulated Raman scattering in the same active medium, namely crystalline silicon doped by bismuth (Si∶Bi).

Atmosphere Activity Measurement by LED Raman Mini Lidar [PDF]

EPJ Web of Conferences, 2020
The LED mini lidar was improved to monitor Raman scattering echoes. The Raman scattering signal indicates a certain gas concentration and it can distinguish the target from the other materials.

Stimulated Raman scattering of water maser lines in astrophysical plasmas [PDF]

, 1999
Radiative transfer equations are derived and solved for the stimulated Raman scattering of water maser lines in the astrophysical plasmas with electron density of about 10^6 - 10^7 cm-3.

Stimulated Raman Microscopy Implemented by Three Femtosecond Laser Sources [PDF]

EPJ Web of Conferences, 2021
In this work, the implementation of a femtosecond Stimulated Raman Scattering microscope, equipped with three femtosecond laser sources: a Titanium-Sapphire (Ti:Sa), an optical parametric oscillator (OPO), and a second harmonic generator (SHG); is ...

Generation of frequency shifted picosecond pulses with low temporal jitter [PDF]

, 1984
Transient stimulated Raman scattering is used for the generation of a frequency shifted picosecond light pulse; part of this Raman shifted pulse is subsequently coherently scattered at a material excitation of a second Raman cell.

Suppressing stimulated Raman side-scattering with vector light

Matter and Radiation at Extremes, 2023
Recent observations of stimulated Raman side-scattering (SRSS) in different laser inertial confinement fusion ignition schemes have revealed that there is an underlying risk of SRSS on ignition. In this paper, we propose a method that uses the nonuniform

Enhancement of field generation via maximal atomic coherence prepared by fast adiabatic passage in Rb vapor [PDF]

, 2003
We have experimentally demonstrated the enhancement of coherent Raman scattering in Rb atomic vapor by exciting atomic coherence with fractional stimulated Raman adiabatic passage.

Phase aspects of (broadband) stimulated Raman scattering

Reviews in Analytical Chemistry, 2012
The phase of the molecular response can be exploited to improve selectivity without sacrificing speed in both narrowband and broadband coherent anti-Stokes Raman scattering (CARS) microscopy, both of which will be considered in this review of the work ...
