Abstract:
1. A spectrometer, comprising; a light source, the light source being able to produce a pump pulse of coherent light and a probe pulse of coherent light, the pump pulse and the probe pulse each having a frequency profile, a phase profile, a polarization profile and a temporal profile; a pulse shaper, the pulse shaper being able to modify the frequency profile, the phase profile and the temporal profile of the pump pulse; a sample of interest, wherein the pump pulse and the probe pulse contact the sample of interest, and wherein the sample of interest emits an electromagnetic field having a frequency profile, a polarization profile, a phase profile and a temporal profile after contacting with the pump pulse and the probe pulse; a delay line, the delay line being able to delay when the probe pulse contacts the sample of interest relative to when the pump pulse contacts the sample of interest; a detector, the detector being able to output a signal indicative of the frequency profile and the temporal profile of the electromagnetic field emitted by the sample of interest; a processor, operatively connected to the light source, the pulse shaper, and the detector, the processor being able to convert the signal from the detector into a multidimensional spectrum.
