Abstract:
1. An all-fiber-based Chirped Pulse Amplification (CPA) laser system comprising all fiber-based optical components further comprising: a fiber mode-locking oscillator configured for generating a laser pulse for projecting to a fiber stretcher configured for stretching a pulse width of said laser pulse, wherein said stretcher further comprising a self-phase modulation (SPM) assisted photonic crystal fiber (PCF) single mode (SM) fiber stretcher, wherein said SPM assisted PCF-SM stretcher further comprising a nonlinear PCF, wherein said nonlinear PCF further configured for generating a spectrum broadening to more than 1000 nm for a laser power as low as 40 mW and a peak power of 40 KW; and a multistage amplifier configured for amplifying said laser pulse and a high-order dispersion compensating compressor configured for compensating high-order dispersions and compressing said pulse width of said laser pulse.
