Abstract
Nonlinear pulse compression is demonstrated using 0.7-mJ, 80-fs, 1.55-µm pulses generated from an optical parametric chirped-pulse amplification system. By focusing the pulses into 9 pieces, 200-µm-thick quartz plates, the involved multiple plate continuum generation and the subsequent pulse compression using a Fourier pulse shaper can ultimately produce pulses with a nearly transform-limited duration of 20 fs.
