Generation of terawatt 10-fs blue pulses by compensation for pulse-front distortion in broadband frequency doubling

Opt Lett. 2004 Dec 15;29(24):2929-31. doi: 10.1364/ol.29.002929.

Abstract

Pulse-front distortion as a result of broadband frequency doubling (BFD) has been compensated for over a 3-cm beam diameter by use of a telescope image relay system. As a result, distortion-free blue pulses with a peak power of 1.4 TW and a pulse width of 10 fs have been generated with a 10-Hz Ti:sapphire laser by use of this modified BFD configuration.
