摘要

A novel technique for high-power extracavity pulse compression with a nonlinear solid material is demonstrated.Before spectral broadening by self-phase modulation in the solid material, a short filament generated in argon is used as a spatial filter, which works for a uniform spectrum broadening over the spatial profile. Compensated by chirped mirrors, a 15-fs pulse is generated from a 32-fs input laser pulse. A total transmission larger than 80%after the solid material is achieved.
