Abstract

We present a 100-kHz deep-ultraviolet (DUV) laser system that generates 40-fs pulses. A 520-nm pulse generated by a noncollinear optical parametric amplifier pumped by the second harmonic of a Ti:sapphire laser is converted into 226- and 260-nm DUV pulses simultaneously with pulse energies of 250 and 130 nJ (average powers: 25 and 13 mW), respectively. The DUV pulses were estimated to have durations of ca. 40 fs by crosscorrelation measurements based on (1 + 1') two-color ionization of gaseous nitric oxide.
