To provide laser condition detection equipment capable of detecting highly reliably a condition using a self-coupling effect of a semiconductor laser element.

This laser condition detection equipment for analyzing an irradiation beam superposed with an interference signal generated by the self-coupling effect in the semiconductor laser element to detect a condition up to a measuring object, using the semiconductor laser element for emitting a wavelength-modulated laser beam toward the measuring object, and for introducing the laser beam reflected by the measuring object, is provided, in particular, with a condition detecting photoreceiver provided to receive only the irradiation beam emitted from the laser element, and an object detecting photoreceiver provided to receive only the reflected beam by the object.
