Abstract

Propagation of noncollinear generated second harmonic and sum frequency beams of ultrashort light pulses has been studied. An interference maximum in the far-field intensity distribution of the beams has been observed. The position of the maximum depends on the time delay between the interacting pulses. On the basis of this effect a technique to measure the lengths mismatch of two cavities and a technique to measure the time delay between two pulses with differing frequencies in a single laser shot have been developed.
