Measurement of phase shifts introduced by nonlinear optical phenomena on subpicosecond pulses.
A new method for the coherent characterization of subpicosecond optical pulses after propagation through a nonlinear medium (i.e., with frequency broadening) is described. The phase shift on a single pulse introduced by the nonlinearity can be measured with a high dynamic range. We report as one application of this technique a measurement of the self-phase modulation incurred by an 800-fsec pulse after the pulse propagates along a dispersive single-mode optical fiber.
