Generation of 1.8-mJ, 2.5-μm, Sub-3-Cycle Laser Pulses via Hollow-Core Fiber Pulse Compression

Abstract

We report on nonlinear compression of 2.5-μm, sub-100 fs laser pulses using a noble-gas-filled hollow core fiber. MgF₂ wedges are used to compress the pulse and perform dispersion-scan. Sub-3-cycle, 1.8-mJ pulses are obtained after compression.
