OBSERVATION OF MODE LOCKING AND ULTRASHORT OPTICAL PULSES INDUCED BY ANTISOTROPIC MOLECULAR LIQUIDS

Abstract
Mode locking and ultrashort pulses have been produced in a giant‐pulse ruby laser with heated nitrobenzene (T > 110°C) or α‐chloronaphthalene (T > 62°C) inside the optical resonator. 10−11‐sec pulses were observed with the two‐photon fluorescence technique.
