Relativistic Doppler reflection of THz light via photo-induced carriers in Si

Kono, Nanase

Photo-induced plasma acts as a flying mirror with a velocity which is identical to that of pump light because plasma is generated with a proceeding of pump light into a semiconductor. Then, a counter-propagating THz light is up-shifted via relativistic Doppler reflection. In this study, sample semiconductor is silicon, and we investigated a Doppler reflection of THz light by observing an intensity spectrum and waveform of THz light. From the pump energy dependence, phase and frequency shifts of THz light is increased with pump energy. We constructed a model in consideration of phase shift and Doppler reflection.
