Abstract
A chirped pulse amplification (CPA) system and method is described wherein the pulse is stretched using multiple passes through a Bragg grating or compressed using multiple passes through a Bragg grating. A switch may be used to control the number of passes through the Bragg grating, thus, tuning the compressed or the stretched pulse width. The pulse may be directed through an amplifier between the multiple passes through the Bragg grating to apply amplification to the stretched pulse multiple times. The Bragg grating may include a fiber Bragg grating, a volume Bragg grating, or a Bragg waveguide.
