PROBLEM TO BE SOLVED: To provide an optical sampling waveform observing apparatus capable of making effective use of at least one of a signal of light to be measured having passed through a nonlinear optical crystal of a sampling optical pulse. SOLUTION: The optical sampling waveform observing apparatus 10 allows a signal of light to be measured L1 and a sampling light pulse L2 from a light source 11 for the sampling light pulse to be incident on the nonlinear optical crystal 13, and light L3 of their sum frequency generated in the optical crystal 13 is received by a photodetector 14, to observe the waveform of the light signal L1. A photodetector 17 receives the light pulse L2 having passed through the optical crystal 13, and a pulse timing control circuit 18 controls the timing of emission from the light source 11, on the basis of the received light signal from the photodetector 17.
