  "abstract": "Single-shot coherent Rayleigh-Brillouin scattering (CRBS) requires dual colour, frequency, and pulse duration agile laser systems, currently available only in laboratory layouts. In this work, we present a compact, portable, and robust next generation laser system that meets all of these requirements. Key features include an integrated master-slave seed laser design for stable frequency chirping, fiber-coupled acousto-optic modulator (AOM) gated pulse shaping for long-term thermal stability, and customized amplification stages in a rugged, portable enclosure which simplifiy the alignment and maintenance process. The system in this implementation can deliver up to $450$~mJ per arm, chirp rates up to $\\sim22$~MHz$/$ns, and arbitrary temporal profiles within $\\sim25$~ns to $\\sim1$~$μ$s. This laser system is validated by measuring the neutral number density of an atmospheric plasma jet, and a two-dimensional temperature map is constructed, demonstrating lab-grade diagnostics for field deployment.",
