Description
Summary:In this paper,the output characteristics of passive <i>Q</i>-switched ytterbium doped pulse fiber lasers for distance measurement was studied.Besides,the effects of saturable absorber length and gain fiber length on output power were studied by simulation.Under the condition that the pump source power was 5 W,the simulation results showed that the output pulse width was 0.8 μs,the pulse peak power was 26 W,the average power was 2 W and the pulse energy was 20 μJ.When the object reflectivity was 10%,and when the detection distance was 200 m,and when the atmospheric transmittance was 100%,the minimum power returned was 3.9&#215;10<sup>-7</sup> W.
