Abstract:
Apparatus for transporting a laser-pulse from a pulsed-laser to a receiver, comprising:a pulse-expander, an optical-fiber, and a pulse-compressor; said pulse-expander arranged to receive and temporally expand the laser-pulse from the pulsed laser;said optical-fiber positioned to receive the laser-pulse from said pulse-expander and transport the pulse to said pulse-compressor, said pulse becoming temporally-compressed as a result of said transporting;said pulse-compressor including a block of optically-dispersive material through which the laser-pulse from the optical-fiber passes, said block further temporally-compresses the laser-pulse and delivers the laser-pulse to the receiver, andwherein said pulse-compressor includes an optical arrangement that causes the laser-pulse to follow a zigzag path through said block of optically-dispersive material such that the net dispersion for a given length of the optically-dispersive material is increased.
