Paper Abstract

Chirped pulse amplification is a durable and widely used scheme for producing short pulses with duration less than 1ps and pulse energies from μJ to even mJ levels. The compressor unit needs to be able to handle high peak powers and is therefore traditionally made out of free space diffraction gratings. The stretcher unit, on the other hand, only has to handle low peak power and can therefore be realized with a dispersion managed fiber. We review our work on stretcher fiber design and dispersion managed modules in the Ytterbium gain band and Erbium gain band and present a modified stretcher fiber for managing numerically higher third and fourth order dispersion. The modified design allows for a lower incident angle on the compressor gratings and thereby reducing the grating separation and compressor size.
