How do I do dispersion pre-compensation?

For extremely short pulses, such as few-cycle pulses, this can best be done with a combination of Dispersion Compensating Mirrors (DCMs) and wedges. DCMs compensate the dispersion in discrete steps, and adding a pair of wedges enables continuous adjustment of the compensation to reach the optimal amount needed to gain the shortest pulse duration at the target. Alternatively, these can be combined together in a “pre-chirper” with motorized control to make regular alterations easier.
