摘要：
A laser device includes at least one light source; a delivery fiber that is configured to propagate of laser light emitted from the light source; and a first light detection unit and a second light detection unit configured to detect a part of light propagating in a direction opposite to a propagation direction of the laser light through the delivery fiber. The first light detection unit detects first light included in a wavelength band of visible light. The second light detection unit detects second light included in a wavelength band of near-infrared light.
