Chirped-pulse amplification with a fiber stretcher and a grism compressor Academic Article uri icon


  • In chirped-pulse amplification (CPA) lasers, pulses are temporally stretched by a factor of approx.103, and to achieve good pulse compression it is necessary that the dispersion of the compressor match that of stretcher. This paper presents an 'ideal compressor' that matches the second- and third-order dispersion of fibers in the normal regime. This compressor consists of a pair of Carpenter gratings or 'grisms' (transmission gratings written on to prisms) CPA of 135-fs pulses with a 100-meter single-mode fiber stretcher is demonstrating. This compression factor of approx.750 is, to our knowledge, the highest reported single-stage compression factor from a fiber. The grism compressor should lead to the development of compact, ultrashort-pulse amplifier systems for 'real-world' applications, including two-photon microscopy, micromachining, and opthalmology.
