Abstract
We exploit second-harmonic generation with large group velocity mismatch to efficiently convert femtosecond pulses into tunable narrowband picosecond pulses. The temporal shape of the picosecond pulses can be tailored by engineering the aperiodically poled crystal. (C) 2008 Optical Society of AmericaFile in questo prodotto:
