摘要
An all-fiber optical laser pulse multi-pass stretcher using a chirped fiber Bragg grating （CFBG） is demon- strated. Pulses from a 1 053-nm mode-locked fiber seed oscillator are stretched by multiple passing through a chirped fiber grating set in a fiber regenerative amplifier structure. We stretch the pulse from 16 ps to 1.855 ns after it transmits seven loops in the stretcher. The main factors that affect the stretching results are discussed.
