Abstract

We present a comprehensive investigation of the period chirp, a detrimental effect originating from the lithographic step in the fabrication of holographic gratings. Starting from the origin of the period chirp we discuss its measurement, its effects on the compressed pulses when chirped gratings are used in pulse compressors, and finally, we show possible ways to eliminate the period chirp directly in the fabrication.
