Abstract

We report here our recent observations of low J-value Stokes and anti-Stokes lines from stimulated rotational Raman scattering (SRRS) in long air paths with a large Fresnel number beam at a pump wavelength of 1053 nm. The spectral and temporal dynamics of SRRS is important to our understanding of SRRS as applied to the propagation of large-aperture beams in laser systems for fusion research and in defense applications.^1,2 An example of this is the proposed implementation of broad bandwidth and spatial incoherence for target irradiation experiments in the field of laser-plasma interactions.
