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.
