It is possible to perform single wavelength pump-probe experiments. In this case the samples can be excited with 800, 400 or 266 nm light and probed with a single wavelength from the OPA (240 – 20000nm). The pump light is modulated with a chopper and the pump-probe signal is extracted using a lock-in amplifier. This method is complementary to the transient absorption and reflectance measurements with white light as it allows access to a range of probe wavelengths in the NIR/MIR (1600 – 20000 nm) not available in those experiments.
