SRS in the strong-focusing regime for Raman amplifiers
Abstract:
The theoretical analysis of stimulated Raman scattering (SRS) in crystalline amplifiers with a tightly-focused pump geometry is presented. We predict the minimum Stokes seed power required for an efficient Raman power amplifier and verify this result experimentally. Conversion of a pump to a Stokes beam in a single-pass diamond amplifier is demonstrated using nanosecond pulses with gains of 5.8 from a 1.2-kW peak-power Stokes seed beam. The results demonstrate the possibility of amplifying and combining high-power continuous-wave lasers using current diamond Raman laser technology.

Raman Spectroscopy Instrumentation: Overview
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
