High-precision optical field simulation for end-pumped laser amplifiers using a seed beam reconstruction approach

Le résumé fourni par la source

A simulation model is proposed to explore the evolution of the optical field in a three-stage end-pumped laser amplifier, utilizing a seed beam reconstructed in terms of both intensity and wavefront. Experimental validation demonstrates the efficacy of the proposed reconstruction scheme through direct comparison with an ideal Gaussian seed model. The reconstructed model exhibits superior accuracy in replicating the optical field evolution dynamics, particularly in multistage master oscillator power amplifier (MOPA) configurations where the Gaussian approximation fails to maintain simulation fidelity. This advancement significantly elevates the theoretical precision of MOPA laser system modeling, providing key theoretical guidance for the simulation analysis and overall design of high-power MOPA laser systems.
