Abstract
Apparatus for transporting a laser-pulse from a pulsed-laser to a receiver includes a pulse-expander, an optical-fiber, and a pulse-compressor. The pulse-expander is arranged to receive and temporally-expand the laser-pulse from the pulsed laser. The optical-fiber at its proximal end to receive the laser-pulse from the pulse-expander and transport the laser-pulse to the pulse-compressor. The pulse-compressor is arranged to receive the laser-pulse from the optical-fiber, temporally-compress the laser-pulse, and deliver the laser-pulse to the receiver. The pulse-compressor includes a block of optically-dispersive material, the temporal-compression being effected by an optical arrangement that causes the laser-pulse to follow a zigzag path through the block of optically-dispersive material. The pulse-expander may be arranged to provide variable third-order dispersion of a laser-pulse being expanded. The pulse compressor may be included in a handpiece attached to the distal end of the optical-fiber.
