Technique and apparatus developed to reduce speckle in unmodulated laser pulses, using reduced number of optical fibers. Expected to decrease costs of bundles of optical fibers used to transmit unmodulated laser pulses. New apparatus reduces speckle in optically transmitted, unmodulated laser input pulse by introducing number of independent delays into pulse.
