We have proposed and developed a new feedback control system to automatically minimize the pulse duration of an ultrafast laser using a two-photon absorption detector that has a Gires–Tournois interferometer (GTI) for compensating the positive group delay dispersion of the laser cavity. The signal of the two-photon detector is inversely proportional to the pulse duration when the average power, repetition rate, and pulse shape are maintained. The minimization of the pulse duration is accomplished by adjusting the voltage applied to the GTI to maximize the two-photon signal. We demonstrated the control of pulse duration minimization with the developed system.
