Using the ray-tracing method,we demonstrate that a grating-telescope stretcher is the conjugation of a grating pair compressor.We present an analytical formula for calculating the phase dispersions of the grating-telescope stretcher.The computer simulation with the formula demonstrates that there exists an optimal material dispersion for an amplification system,with which we can achieve the largest dispersion-free bandwidth.
