Abstract
We demonstrate the pulse compression of the picosecond laser system with an all fiber master oscillator power amplifier configuration containing a chirped volume Bragg grating (CVBG) at 1064 nm. We use a passive mode-locked Yb doped fiber laser with a 10 ps pulse width at a 45 MHz repetition rate for the master oscillator. Optical pulses from the oscillator are amplified by a single stage fiber amplifier. Then the spectra of amplified pulses are chirped, and the spectral widths spread due to self phase modulation (SPM) in the fiber amplifier. The chirped pulses are compressed by CVBG. In this system, we achieve the pulse width of 2.89 ps, and average output power of 1.3 W.
