We recently introduced a new compact pulse stretcher [Opt. Lett. 22, 811 (1997)] that uses standard curved gratings and has several advantages over other systems. It provides positive group-delay dispersion and adequately matches the standard grating pair compressor, which makes it useful in chirped-pulse amplification systems. We analyze the conditions that the different parameters of the stretcher must satisfy to be afocal as well as the problem of chromatic aberrations.
