| Sumario: | By combining phase modulation and dispersive transmission on a given time-varying in-put signal, we propose an optical device for produc-ing ultrashort light pulses of high optical power. We derive the relationship between the required proper-ties of the input signal and the device parameters in order to optimize the energy concentration in the output optical pulses. The high-order aberrations effects of the time lens which perform the phase modulation are considered. Besides, the differences on the obtained pulse shape when the input signal has a gaussian or a super-gaussian envelope are illus-trated. Finally, some numerical simulations are shown which illustrate the feasibility of the method. |
