Abstract
The model of the pulse front tilted by a folded reflecting telescope used as a beam expander in the chirped pulse amplification system is developed, and the relationship between the pulse front aberrance and the parameters of the telesco pe is discussed. It is found that the effect of pulse front aberrance on the bea m is too strong to be ignored when the pulse duration is less than 100fs. An e ffective method is presented to overcome this problem.
