RADIATION PULSE GENERATION
A radiation pulse generating assembiy comprises a radiation generator (1) such as a laser for generating pulses of radiation having pulse widths in the order of pico seconds. The pulses from generator (1) are coupled into an optical fibre (2) which causes the pulses to undergo Raman scattering to ge...

| description | A radiation pulse generating assembiy comprises a radiation generator (1) such as a laser for generating pulses of radiation having pulse widths in the order of pico seconds. The pulses from generator (1) are coupled into an optical fibre (2) 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 (3) filters out the initial pump wavelength while a second filter (4) downstream of the first filter (3) is tunable to select reduced width pulses within a desired wavelength band. |
