The photoconductivity in CdS single and polycrystals was investigated by using mode-locked Ndglass laser pulses for excitation and was found to exhibit a power law I to the 3.0 plus or minus 0.2 power, where I is the peak excitation intensity. The three-photon absorption coefficient estimated from the photoconductivity measurement agreed well within an order of magnitude with the theoretical values.
