Abstract
For many ultrafast experiments it is desirable to have synchronized subpicosecond pulses at multiple wavelengths. Recently, synchronously pumped parametric oscillators (SPPO) have been used to satisfy this requirement as well as produce ultrafast pulses at wavelengths beyond 1 µm. In this paper, we demonstrate the synchronism inherent in an SPPO by measuring a 100 fsec cross-correlation between the pump and signal pulses. We then use the synchronization between the signal and idler to generate pulses at longer wavelengths by difference frequency mixing in lithium niobate and silver gallium sulfide.
