Abstract
The recent development of quartz-prism-controlled1,2 and mirror-dispersion-controlled3 (MDC) Ti:sapphire lasers has allowed the generation of optical pulses with durations of 10 fs. The typical output-pulse energy of these lasers is of the order of a few nanojoules. Since higher pulse energies are required for many applications, a number of schemes based on the concept of chirped-pulse amplification (CPA) have been devised. Recent advances in CPA have resulted in the amplification of 30-fs optical pulses to beyond the terawatt level at a repetition rate of 10 Hz. 4,5 Gain narrowing and residual high-order dispersion due to an imperfect matching between the pulse stretcher and the compressor have been identified as the major performance-limiting effects.
