Abstract

A terawatt KrF/Ti:sapphire hybrid laser system with a high contrast between amplified spontaneous emission and the main pulses has been developed with an output energy of 130 mJ in 130-fs pulses. An efficient frequency-tripling scheme with Ti:sapphire is demonstrated with an efficiency of 11% in the 100-fs regime with LiB3O5 and β-BaB2O4.

KrF/Ti:sapphire hybrid laser system. The system consists mainly of a three-stage Ti:sapphire amplifier chain, a frequency tripler, and a wide-aperture KrF amplifier. FR, Faraday rotator; DM’s, dichroic mirrors; OSC, oscillator.

Fig. 2
Fig. 2

Schematic diagram of the frequency tripler. The fundamental and second-harmonic beams separated by a dichroic coating on one half of the beam splitter were overlapped in mixing crystal by a dichroic coating on the other half of the beam splitter after 90-deg polarization rotation and an appropriate delay.

Fig. 3
Fig. 3

Spectral change in the hybrid system: Spectra correspond to (a) after frequency doubling, (b) after frequency tripling, and (c) after amplification by KrF. LBO was used for doubling, and BBO was used for tripling.

Single-shot autocorrelation traces of KrF laser pulses (a) before and (b) after a prism compressor.
