La pression des gaz est sensiblement la pression atmosphérique. La disposition transverse permet d'avoir des champs électriques importants sur de courtes distances. L'excitation est impulsionnelle. Les lasers TEA sont donc des lasers impulsionnels, pouvant émettre des énergies allant jusqu'à la centaine de joules, avec des durées d'impulsions inférieures à la microseconde. 1, record 5, French, - laser%20TEA

A measure of the cleanliness of air is the atmospheric visibility. That visibility is generally degraded by atmospheric aerosols. The nephelometer is a device which measures the light scattering capability of the atmosphere and thus provides a measure of visibility. The light source in an integrating nephelometer provides excitation for particulates which scatter light into a cone between 10 and 170 degrees of the optic axis. The scattered light is detected with a photomultiplier. The signal is proportional to the scattering coefficient of the aerosol and empirical relations are available to relate this measure to the mass concentration of ambient aerosols. 1, record 15, English, - integrating%20nephelometer
