Abstract

The invention relates to a miniature laser-induced water condensation simulating device. The device is characterized in that a cavity is a small hexahedral closed cavity synthesized by six red copper blocks; a plurality of densely distributed small slots are uniformly formed in the inner walls of the red copper blocks on the top and bottom of the cavity; the outer surfaces of the red copper blocks on the top and bottom are in full contact with cooling surfaces of semiconductor refrigerating sheets; the heat dissipating surfaces of the semiconductor refrigerating sheets are in full contact with the heat dissipating sheets of the red copper blocks; the semiconductor refrigerating sheets connected in series through a guide wire in a serial manner are connected to a direct current power supply source; and a humidity adjusting channel is also arranged on a side surface of the cavity to be connected to a humidity adjusting device. The device provided by the invention is more compact and simple in structure. The whole device is more miniature, is convenient to move, can realize a low-temperature environment without a temperature gradient, and is suitable for more conveniently researching and analyzing a laser-induced water condensation phenomenon.

Description

technical field [0001] The invention relates to laser-induced water condensation, in particular to a miniaturized laser-induced water condensation simulation device. Background technique [0002] In recent years, with the maturity of femtosecond laser technology, the application of ultra-intense and ultra-short laser pulses in remote sensing, lightning control, and laser-induced water condensation has attracted widespread attention. The ultra-intense and ultra-short laser pulse originates from a dynamic balance between the self-focusing effect produced by the optical Kerr effect and the defocusing effect formed by plasma in the medium. The plasma channel formed by this dynamic balance is commonly known as femtosecond light filament. Femtosecond light filament can produce supercontinuous white light, form a cone-shaped radiation, and clamp light intensity. Laser pulses have great potential applications in femtosecond laser-induced water condensation. Therefore, it is of gre...
