Experimental device for simulating interaction between femtosecond lasers and cirrocumulus and manipulation method thereof

Abstract

Provided is an experimental device for simulating an interaction between femtosecond lasers and cirrocumulus. The device comprises a femtosecond laser device, a lens, a low-temperature cold cabinet, a temperature and humidity detection device, an aerosol generator, a scanning electromobility particulate particle size spectrometer, a digital camera and a beam collecting device, wherein femtosecond laser pulses are focused by the lens to enter an ultra-low temperature high-humidity cavity, femtosecond laser pulse filamentation is conducted in the cavity, accordingly the interaction between laser filaments and simulated cirrocumulus is studied, cloud droplets in the cavity are led to phase change, and processes of moisture condensation and sedimentation are induced. The device simulates the temperature and humidity environment of the cirrocumulus precisely, is simple in structure, safe and convenient to operate and low in price, is suitable for studying and analyzing the phenomenon that the cirrocumulus which is rich in ice crystals interacts with the lasers so that the water condensation and sedimentation can be generated, and is also suitable for analyzing and studying the interaction study between other cloud-mist conditions and the lasers.

Description

technical field [0001] The invention relates to the field of artificially induced rainfall, in particular laser-induced water vapor condensation and settlement inside cirrocumulus clouds, in particular a small experimental device for simulating the interaction between femtosecond laser and cirrocumulus clouds and a control method thereof. Background technique [0002] Artificial weather modification refers to artificially affecting the physical and chemical processes of the local atmosphere through scientific and technological means under appropriate conditions in order to avoid or mitigate meteorological disasters, rationally use climate resources, and achieve rain and snow enhancement, hail prevention, rain elimination, and fog elimination. , anti-frost and other activities. [0003] So far, the traditional method has been to spread small particles of dry ice, silver iodide and other salts in the clouds. Since artificial rainfall and snowfall have important influences on ...
