This invention is a distance measurement rangefinder. The proposed laser rangefinder contains, serially connected, pulse laser with an optical system, a pulse amplifier and a regulated pulse generator; also, serially connected, a photoreceiver based on an avalanche photodiode with an optical system, conjugate to that of the laser, an amplifier of photo-detected signals, comparator, time-interval meter, and an object detection indicator. This rangefinder is unique in that the pulse amplifier features an additional output, connected to which is a second laser with an optical system, conjugate to that of the first laser and avalanche photodiode; and an additional second input connected to the first input of the pulse amplifier, to the first output of the regulated pulse generator and to the first input of the time-interval meter.
