    Abstract: A device for emitting a laser beam comprises, in a housing, a laser-emitting component emitting a laser beam and mounted on a base, a heat-dissipating component, at least one collimating lens, and a lens mounting. The heat-dissipating component dissipates the heat produced by the laser of the laser-emitting component and secures the base of the laser-emitting component. The heat-dissipating component has a positioning mark and at least three holes for centering pins machined together with the positioning mark. The lens mounting secures the lens opposite the laser-emitting component and is positioned relative to the heat-dissipating component by at least three centering pins positioned in the holes of the heat-dissipating component.

    Abstract: The photoacoustic device for measuring the quantity of at least one gas. The Helmholtz-type esonant container comprises at least two tubes closed at their ends and linked together, close to each of their respective ends, by capillary tubes of diameter lower than the diameter of the parallel tubes. Each of the two radiant laser energy sources is physically separated and adapted to supply an excitation energy to the gas in the container at a different emission wavelength. The modulation means modulates the excitation energy supplied by each laser energy source with a modulation frequency corresponding to the acoustic resonance frequency of the container. At least one acoustoelectric transducer disposed on one of the tubes detects the produced acoustic signals produced and supplies an electric signal representative of the gas concentration in the container.
