Compression after compressor: threefold shortening of 200-TW laser pulses

Compression of a 12-J laser pulse from 63 to 21 fs is experimentally demonstrated for a beam 18 cm in diameter. The compression is implemented for a pulse freely propagating in glass under conditions of self-phase modulation and subsequent compensation for dispersion under reflection from dispersion...

Zusammenfassung:	Compression of a 12-J laser pulse from 63 to 21 fs is experimentally demonstrated for a beam 18 cm in diameter. The compression is implemented for a pulse freely propagating in glass under conditions of self-phase modulation and subsequent compensation for dispersion under reflection from dispersion mirrors. This simple and inexpensive technique for increasing multiply the pulse power is characterised by almost 100 % energy efficiency and can be used at the output of any ultra-high-power laser, without any changes in its optical scheme.
