Abstract:

Subject of study. Development of a small­sized pulsed laser rangefinder with a passive thermal stabilization system. Objective. Creation of a sample of a laser rangefinder generating pulsed laser radiation with wavelength l = (1,57 ± 0,04) µm. Method. A theoretical study of the influence of the rangefinder operating wavelength on the propagation of laser radiation in the atmosphere was carried out by the finite difference method in a time­dependent formulation. The mode composition of radiation was estimated using a standard numerical solution of the Fresnel–Kirhhoff diffraction integral. The methods of pyroelectric registration were used for estimation of energy parameters of laser radiation. Main results. The small­sized laser rangefinder generating laser radiation in the near­IR range at a wavelength of (1,57 ± 0.04) µm with a pulse repetition rate of up to 20 Hz and a pulse energy of up to 17 mJ has been developed. The rangefinder emitter is built on the basis of a composite stable semi­confocal optical resonator. In one of the resonator parts a nonlinear passive conversion of radiation l = (1.064 ± 0.025) µm, generated by active media based on a stoichiometric Nd:YAG single crystal, in signal wave with l = (1.57 ± 0.04) µm occurs. Scientific novelty. The research demonstrates the possibility of maintaining stable generation at a temperature mismatch between the absorption spectrum of the active media and the emission spectrum of the laser diode bar by up to 22 nm, which makes it possible to abandon the use of a thermal stabilization system of the diodes bar. Practical significance. It is shown that the use of radiation with l = (1.57 ± 0.04) µm is more preferable for tasks of pulsed laser ranging in comparison with radiation with l = (1.064 ± 0.025) µm because of less scattering on atmospheric aerosol. The active media is pumped by quasi­continuous wave (QCW) multispectral laser diodes array with total average radiation pulse power of 2200 W, which makes it possible to abandon active thermal stabilization and optimize the mass and dimensional parameters of the product.
