N2 - The performance of the spin-dependent transient rotation (STR) for a multiple-quantum-well (MQW) etalon is studied. An on/off contrast of 4:1 obtained for a pump pulse energy of 50 Fj/μ2at room temperature is larger than that obtained by other picosecond switching methods using etalons. The experimentally observed polarization-rotation angle of the probe beam has been found to be proportional to the total well thickness, which is consistent with the theoretical prediction. It is predicted that the contrast can be improved to over 20:1 for a pump pulse energy of 50 Fj/μ2by using a MQW etalon with a total well thickness of 1 μт.
