Abstract
We have observed far‐infrared radiation generated by picosecond pulses in LiNbO3 with several different phase‐matching conditions. The output spectra,analyzed by a far‐infrared Michelson interferometer and by a Fabry‐Perot interferometer, agree well with theoretical calculations. The laser pulsewidth deduced from these measurements was about 2 psec in comparison with 5 psec obtained from two‐photon fluorescence measurements.Keywords
