Lower frequency region mid-infrared spectroscopy by chirped pulse upconversion
Department of Physics and Astronomy, Faculty of Sciences, VU University, The Netherlands
UV/visible pump, mid-IR probe spectroscopy measurements based on the chirped upconversion method were expanded to the frequency region below 1800cm−1 with the nonlinear optical crystal AgGaGeS4. Pump-probe experiments were demonstrated with GaAs and the photoreceptor protein Slr1694.
