PROBLEM TO BE SOLVED: To provide a laser measuring device capable of changing a peak output of pulse range finding light emitted toward a measuring object.SOLUTION: The laser measuring device comprises: a light-emitting part 6 emitting pulse range finding light 28; a light receiving part receiving reflection pulse range finding light; and a control arithmetic part controlling the light-emitting part and calculating a distance to a measurement target object based on a reception signal from the light receiving part. The light-emitting part has: a light emission source 17 emitting excitation laser light 22; spot diameter changing means 20 for changing a spot diameter of the excitation laser light; and an optical resonance part 21 emitting the excitation laser light received via the spot diameter changing means as pulse range finding light.SELECTED DRAWING: Figure 2 |
