Magneto-optical effects in quantum wells irradiated with light pulses

A method to detect and investigate the magnetopolaron effect in semiconductor quantum wells in a strong magnetic field, based on pulse light irradiation, and measuring the reflected and transmitted pulses, is proposed. It is shown that a beating amplitude on the frequencies, corresponding to the magnetopolaron energy level splitting, depends strongly on the exciting pulse width. The existence of time points of the total reflection and total transparency is predicted. High orders of the perturbation theory on electron-electromagnetic field interaction are taken into account.
