Third order autocorrelation study of amplified subpicosecond laser pulses
Abstract
The optical Kerr effect shutter method is employed to determine the temporal width and shape of subpicosecond pulses issued from a passively mode-locked CW dye laser, feeding a three stage amplifier. It is shown that the optical Kerr effect corresponds to a third order correlation and thus contains specific information on the width and shape of the pulse which initiates it. Accurate measurements of these parameters are provided by the large dynamic range that reaches 1000 obtained by using this method. It is determined that average pulses generated by a passively mode-locked CW dye laser and amplified in a three stage setup are described by a symmetrical exponential shape function.
