1. A radiation pulse generating assembly comprising:
- a radiation generator for generating pulses of radiation;
a waveguide into which pulses of radiation at working intensities from the radiation generator are coupled, the waveguide causing the radiation pulses to undergo Raman scattering to generate reduced width pulses with wavelengths lying within a Raman spectrum; and
filtering means into which the reduced width pulses are coupled for selecting reduced width pulses within a desired wavelength band.

Abstract
A radiation pulse generating assembly comprises a radiation generator such as a laser for generating pulses of radiation having pulse widths in the order of pico seconds. The pulses from the generator are coupled onto an optical fiber which causes the pulses to undergo Raman scattering to generate reduced width pulses with wavelengths lying within a Raman spectrum and having widths in the order of femto seconds. A first filter filters out the initial pump wavelength while a second filter downstream of the first filter is tunable to select reduced width pulses within a desired wavelength band.
