Abstract

Considerable advances have been recently achieved in the domain of generation of femtosecond pulses, the first one being the introduction of the colliding pulse mode-locked (GPM) dye laser configuration.¹ These pulses have already been amplified to gigawatt peak power^2,3 without broadening and are able to produce white-light continuum pulses with the same duration. We report here new techniques for generating gigawatt femtosecond tunable pulses by the amplification of a selected part of this continuum and their applications to femtosecond spectroscopy.
