ABSTRACT
As mentioned previously, it should be obvious that the nonlinear fluorescence and Z-scan experimental techniques can be combined by fiber coupling a spectrometer and CCD camera at 90° to the propagation direction. If aligned properly, the fluorescence coupling should be constant along the propagation path, while the pump intensity changes as a function of position by virtue of the changing spot size. The overall increase in processing time is minimal as the instruments can be triggered to pass data independently. The total data increase can be substantial as both incident pulse monitoring for SPM, as well as photochemical measurements, can be obtained simultaneously.
