Improving Fluorescence Kerr Gating — •Ramona Mundt, Gerald Ryseck, and Peter Gilch — HHU Düsseldorf, Germany

With Kerr gating complete fluorescence spectra as a function of time may be recorded in the femto- to picosecond regime[1]. This advantage over fluorescence up-conversion comes at the expand of an increased background. The background is caused by fluorescence leaking through the polarizers and third harmonic generation of the gate pulses. In the contribution it will be shown that the implementation of reference diodes and a correction procedure greatly increases the data quality.
