Abstract :
Chirped-pulse amplification (CPA) has become a common technique for damage-free amplification of the light pulses to TW-level or even higher. The standard CPA systems often use pairing double-prism as pulse compressors, which are preferred over grating based systems. In this paper, we report on the use of negatively chirped high-dispersive mirrors (HDM), with sufficiently high dispersion to overcompensate the positive dispersion of the last prism pair, in order to compress high energy pulses. The test was performed with a commercial Ti:Sapphire multipass amplifier system (Femtopower, Femtolasers GmbH, 2mJ, 1 KHz). The extra dispersion of these HDM´s was compensated by inserting 35 mm of SF57 glass in the stretcher.
