The TR MOKE uses a synchronized 520 nm fs laser with a RF generator in order to access the GHz dynamics in magnetic materials. We use 150 um pitch RF probes in order to contact the sample or we can use a global RF field excitation. The external magnetic field has fixed direction and has maximum of 100mT. The laser spot is stabilized on the measurement grid by active stabilization with 50 nm accuracy.
