Abstract: Short intense lasing pulses of resonant radiation, of the order of 10 13 sec., are produced by employing adiabatic rapid passage of an optical transition of an optically resonant medium, such as K-vapor. The adiabatic rapid passage is achieved in the K-vapor by frequency modulating each pulse of a ruby laser giant pulse source. The modulated pulses are then passed through a fluoronitrobenzene Raman cell to provide an output pulse which has the required power and whose instantaneous carrier frequency sweeps through a resonance having a pair of levels connected by electric dipole transitions in the K-vapor system.
