Temporal pulse quality of a Yb:YAG burst-mode laser post-compressed in a multi-pass cell

Anne-Lise Viotti et al.

Summary: Nonlinear pulse post-compression is an efficient method for producing ultrashort, high-quality laser pulses, but the temporal pulse quality is limited by amplitude and phase modulations. The study characterizes individual post-compressed pulses with high dynamic range, demonstrating nearly constant energy content in the main peak over the burst plateau. This makes multi-pass post-compressed lasers attractive for pump-probe spectroscopy and secondary frequency conversion stages.
