F. Raoult et al., Ultrashort, intense ultraviolet pulse generation by efficient frequency tripling and adapted phase matching, OPTICS LETT, 24(5), 1999, pp. 354-356
We demonstrate efficient frequency tripling of 1057-chirped pulses, using a
dapted chirping and thick KDP crystals. These millijoules broadband pulses
at 352 nm have been compressed to 220-fs duration by use of a UV grating-pa
ir compressor. The technique is scalable to kilojoule petatwatt lasers. (C)
