Abstract

Frequency transformation of high-power Ti:sapphire laser pulses in three β-barium borate crystals resulted in 180-fs optical pulses tunable from 189 to 200 nm. UV pulses with energies of as much as 4 μJ at 200 nm with a 1-kHz repetition rate and pulses with energies of more than 2 μJ at 193 nm with a 20-Hz repetition rate were produced.

Temporal positions of fundamental (solid curves), second-harmonic (dashed curves), and third-harmonic (dotted curves) pulses behind the second crystal for (a) 300-fs and (b) 150-fs fundamental pulses. For better illustration the pulse intensities were normalized.

Fig. 3
Fig. 3

Conversion efficiency as a function of wavelength: η = E(4ω)/[E(ω)E(3ω)]1/2, where E is the pulse energy.

Fig. 4
Fig. 4

Cross-correlation signal at the third harmonic (ω3 = ω4ω1) as a function of the relative delay between fundamental and near-VUV pulses. The solid curve is the calculated cross-correlation function of a 150-fs fundamental pulse and a 180-fs deep-UV pulse with the group-velocity mismatch taken into account and sech2 shaped pulses assumed.

Spectrum of the 193-nm pulses (50 shots accumulated). The bandwidth of 0.4 nm shows the capability of converting 100-fs pulses in the last mixing crystal.
