Notes:
The influence of the spatial distribution of electron-hole plasma on reflectivity measurement is studied in this paper. The plasma density deduced from the reflectivity measurement represents the surface density satisfactorily, if the pump penetration depth is not too short compared with probe wavelength. Besides, when plasma resonance does not take place, the probe incident angle should not be close to Brewster's angle [see, for example, M. Born and E. Wolf, Principles of Optics, 6th ed. (Pergamon, New York, 1980), p. 43] for exponential-like plasma density distribution; otherwise, when the phasma resonance takes place, strong nonlinear recombination and diffusion should be present. In other cases, a general applicable method for data processing is suggested.
