ABSTRACT:
The carrier-envelope phase in a train of optical pulses is varied utilizing the dispersive properties of lossless plates while the total dispersion in transmission is maintained practically constant. The plates include sloped surfaces and are mounted for displacement such that the ratio of the thicknesses of the two plates through which the optical pulses will pass can be varied by displacing the plates so as to shift the carrier-envelope phase in the optical pulses. In one embodiment, the plates include a barium fluoride wedge and a fumed silica wedge, wherein the wedges are bond together to form a composite structure with thicker and thinner portions of the wedges inversely matched.
