Optical pulse amplification by means of a chirp - modulated fiber bragg grating - -

摘要

An apparatus for amplifying of an optical pulse, comprising:Includes generating means for generating an optical pulse in the femtoseconds - region;Expansion a directions (1, 1a, 13), which optically are connected with the means for generating, for reducing the peak amplitude of the optical pulse and for increasing the duration of the optical pulse in the picoseconds - region;Amplifying means (9), the optically with the expander are connected, for increasing the amplitude of the optical pulse, after the optical pulse from the output expander; andDevices for again - compressing (1, 1b), which optically are connected to the reinforcing element for reducing the duration of the optical pulse in the femtoseconds - region, since the optical pulse has been discharged from the reinforcing,wherein the expander and / or - compression means of a chirp - modulated fiber - bragg - grid (1, 1a, 1b) comprises.
