Paper Abstract

A method of measuring distances founded on the optical location of remote objects with the use of ultra-short pulses (USP) of mode-locked lasers is offered. The basic time interval is proportional to the motion time of a sounding USP along the trajectory and is integer quantity proportional to the round-trip time of both laser-counter of a measured interval and of mode-locked laser of sounding USP. Its measuring will be carried out by counting the relevant USP of the CW stabilized on their round-trip time mode-locked laser. Being synchronized with this laser at the moment of the probing USP radiation and being accepted by the photodetector, it has some jitter with the USP of the laser-counter proximate on time, which is detected additionally with the purpose of increasing of the measuring precision. As the laser of a sounding pulse, a pulsing solid-state laser with short-term resonant modulation of losses (STRML-laser) and earlier investigated is proposed. Its properties from the viewpoint of its external dirigibility by electric pulses are described.
