We report the characterization of a new pulse stretcher that provides a linear and positive variation of the group delay as a function of the optical frequency. It consists of a perpendicular chirped-grating pair introduced by Tournois [Opt. Commun. {bold 106}, 253 (1994)] that allows 20-fs pulses to be stretched to 100 ps. The system is tested by short-pulse spectral interferometry. We designed and realized the chirped gratings by phase volume holographic recording in a highly efficient photopolymer. {copyright} {ital 1996 Optical Society of America.}
