We have designed and built an all-reflective pulse stretcher based on an Offner telescope. It uses cylindrical optics to simplify alignment and reduce aberrations. The stretch is {approx}1x10{sup 5} with a bandwidth of 200 nm. The stretcher is to be part of a 10 Hz repetition rate, high-average-power, femtosecond laser. This new design compensates for dispersion in the laser by using gratings of different groove spacing in the stretcher and compressor and a spectral phase corrector plate, made by magneto-rheological finishing, within the stretcher.
