Transform limited subpicosecond pulses have been obtained by parametric conversion of the second harmonic of a short pulse generated by a Nd:glass laser system. The arrangement consists of a KDP followed by a BBO respectively with type II and type I phase-matching, pumped in a travelling wave configuration without any spectral selecting element between them. It provides tunability from 750 to 1770 nm with pulses as short as 0.6 ps. Pulse energies above 50 μJ, with a total conversion efficiency of 13%, have been achieved

Abstract
Transform limited subpicosecond pulses have been obtained by parametric conversion of the second harmonic of a short pulse generated by a Nd:glass laser system. The arrangement consists of a KDP followed by a BBO respectively with type II and type I phase-matching, pumped in a travelling wave configuration without any spectral selecting element between them. It provides tunability from 750 to 1770 nm with pulses as short as 0.6 ps. Pulse energies above 50 μJ, with a total conversion efficiency of 13%, have been achievedI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
