Abstract: Picosecond pulses produced from mode-locked lasers are passed through high Raman coefficient media in which a variety of Stokes and anti-Stokes frequency transitions result. The exiting pulse, which may have an envelope of the same order of magnitude time duration, contains a virtual continuum of wavelengths. The ''''white'''' pulse so produced is then spatially and/or phase divided into a series of ''''component'''' pulses each containing distinct spectral portions of that contained within the white pulse. Component pulses are then processed, for example, by passage through a sample or by passage through a modulator. Information so imparted, generally taking the form of an amplitude change, may serve to spectrally identify the nature of the sample or may serve a communications function.
