Provided is an optical sampling apparatus that samples light to be measured having a pulse waveform, including a sampling light output section that outputs a first sampling light and a second sampling light, both having pulse waveforms of a spectrum different from that of the light to be measured; a first sampling section that includes a first nonlinear optical medium, which causes a nonlinear optical effect by causing at least a portion of the light to be measured and the first sampling light to pass therethrough and outputs light generated by the nonlinear optical effect, and that outputs at least a portion of the light generated by the nonlinear optical effect as a first output light; and a second sampling section that includes a second nonlinear optical medium, which causes a nonlinear optical effect by causing at least a portion of the first output light and the second sampling light to pass therethrough with a temporal overlap in order to output light generated by the nonlinear optical effect, and that outputs at least a portion of the light generated by the nonlinear optical effect as a second output light.
