Claim Text:
1. A scanning probe microscope comprising: a probing needle; a specimen holder in which a specimen is mounted; an oscillator that produces a periodic oscillation to change the probing needle position; a pulse oscillation type laser light source that emits light toward a spot, which is put under measurement by the probing needle, on the specimen; a detector that measures intensity of output light which is output from the specimen by energy spectroscopy; a scanning mechanism that moves the specimen holder; and a control device, wherein the control device is configured to control a relative distance between the probing needle and the specimen, to synchronize shortening of the distance between the probing needle and the specimen and emission of pulse oscillation laser light, and to measure output light peaks associated with a tip enhancement effect which overlap in time with a period of decreased output light from the pulse oscillation laser lights which are blocked by the probing needle, so as to optimize efficiency of tip-enhanced detection.
