Abstract

Summary form only given. We demonstrate a simple and compact chirped pulse amplification (CPA) circuit for boosting both the accessible powers and energies from a femtosecond fiber amplifier. The system is based on a novel pulse compressor, chirped period quasi-phase-matched (QPM) grating, implemented in electric-field poled lithium niobate. A QPM grating compressor is unique in that it combines second-harmonic generation (SHG) and pulse compression in one crystal.
