Carrier-envelope-phase Shifter for Electric-field Shaping of Optical Pulses

Abstract

We demonstrated an active carrier-envelope-phase (CEP) shifter by using a pulse-shaper that controls the spectral phase. Both the CEP-shift and delay-shift are controlled independently by the device. The device was used to actively compensate for a relative CEP-shift imposed by insertion of a dispersive material. We measured the CEP shift by the self-referencing interferometry method and confirmed that the CEP of amplified pulses was actively controlled by the CEP-shifter. The combination of a pulse shaper and CEP-stabilized laser pulses will allow us to design electric fields of optical pulses.
