Direct amplification of terawatt sub-10-fs pulses in a CPA system of Ti:sapphire laser

Opt Express. 2008 Aug 18;16(17):13431-8. doi: 10.1364/oe.16.013431.

Abstract

We have developed a chirped pulse amplification system of Ti:sapphire laser generating a 9.9 fs pulse with a pulse energy of 11 mJ at a repetition rate of 10 Hz. Spectral narrowing during amplification is successfully compensated by using specially designed partial mirrors and broadband high-damage-threshold mirrors. This is the first demonstration, to the best of our knowledge, of the direct amplification of terawatt sub-10-fs pulses in a chirped pulse amplification system of Ti:sapphire laser.
