Implementierung eines nichtlinearen Mikroskops auf Basis der stimulierten Raman-Streuung

Overview

This manuscript describes the implementation of a stimulated Raman scattering (SRS) microscope, integrating an SRS experimental set-up with a laser scanning microscope. The SRS microscope utilizes two femtosecond laser sources, a Ti-Sapphire (Ti:Sa) and a synchronized optical parametric oscillator (OPO).
