Experimental investigation of the stimulated Raman scattering effect in high-power nanosecond superfluorescent fiber source

High Power Laser Science and Engineering, 2023
In this work, we experimentally investigate the dependence of the stimulated Raman scattering (SRS) effect on the seed linewidth of a high-power nanosecond superfluorescent fiber source (ns-SFS). The results reveal that the SRS in the ns-SFS amplifier is

An Adaptive Use Strategy for Solid-State Lasers by Combining Maximum Likelihood Estimation With Model Predictive Control

IEEE Access, 2019
Solid-state lasers are widely applied in various fields, such as material processing, laser marking, and remote sensing. Long lifetime is always required for commercial solid-state lasers in practice.

Circular output from a high power Nd:YLF slab laser [PDF]

, 2008
Neodymium-doped Yttrium Lithium Fluoride (YLF) lasers have traditionally been power-limited by the relatively low tensile strength of the crystal. When power-scaling solid-state lasers, the choice of the gain media geometry, the doping level, and the ...

Characterization of single-crystal synthetic diamond for multi-watt continuous-wave Raman lasers [PDF]

, 2012
A continuous-wave diamond Raman laser is demonstrated with an output power of 5.1 W at 1217 nm. This Raman laser is intracavity pumped by a side-pumped Nd:YLF rod laser: a 43-fold brightness enhancement between the Nd:YLF and diamond Raman lasers is ...
