We demonstrate efficient compression of low-power 6 ps pulses down to 420 fs pedestal free pulses at 1.5 mum in an all-fiber scheme employing only 4 meters of As2Se3 fiber and a tailored chirped fiber Bragg grating.
All-fiber chirped-pulse amplification based on a large-mode-area Er:Yb-doped photonic-crystal fiber is presented. A dispersion-variable hybrid fiber stretcher compensates the peculiar dispersion of the hollow-core photonic-bandgap fiber compressor yielding transform-limited 440-fs pulses with 1-W average power.
We have designed a compact solid compressor by stimulated Brillouin scattering used in a fused silica glass. An 13 ns Nd:YAG laser pulse has been temporally compressed to a 1.2 ns pulse at 1064 nm.
We demonstrate a simple and efficient grism based stretcher/compression system for the first time. 40 fs, 300 muJ pulses are generated at 5 kHz using this unique amplifier design.
Efficient reflection prisms for pulse compression and material-dispersion compensation have been designed and demonstrated in a CPA system. Designs for 800-nm and 1030-nm ultrafast applications are realized using off-the-shelf diffraction gratings.
Parabolic pulses from a similariton amplifier at 1550 nm are compressed using optimized linear compression in photonic bandgap fiber and soliton effect compression in dispersion-flattened highly nonlinear fiber. Transform-limited 20 fs pulses are obtained.
