[ We claim:] [1.] Laser telemetry device operating on the principle of measuring the transit time of a light pulse, comprising:a passively switched microlaser, for emitting light pulses, comprising a solid active medium, a saturable absorbent, an input mirror an output mirror, the saturable absorbent being a thin, saturable absorbent material layer directly deposited on said solid active medium,means for the reception of light pulses reflected by an object and for the detection of a reception time of said pulses,means for the detection of the emission time of light pulses emitted by the microlaser,means for measuring the time interval separating the emission time of a microlaser light pulse from the reception time of a pulse reflected by said object.
