Compression of deep ultraviolet femtosecond pulses using self-phase modulation in bulk material — •Phillip Woschnik, Lukas Bruder, Ulrich Bangert, and Frank Stienkemeier — Institute of Physics University of Freiburg

In many laboratories deep ultraviolet (DUV) pulses at 266 nm are generated by third-harmonic generation of a Ti:Sa femtosecond laser output. Compressing these pulses to short durations is difficult, especially if the pulse duration of the Ti:Sa laser is in the range of > 100 fs. Riedle and co-workers have demonstrated a facile scheme based on self-phase modulation in bulk material, which permits compression of the DUV pulses to < 50 fs [1]. We adapt this scheme in our laboratory and will present the concept and first results.
