The invention relates to a low-concentration soluble carbon nano-tube suspension liquid limiter based on a negative pressure effect. The low-concentration soluble carbon nano-tube suspension liquid limiter consists of soluble carbon nano-tube suspension liquid and a transparent glassware, wherein the soluble carbon nano-tube suspension liquid comprises a carbon nano-tube aqueous solution and surface active agent deionized water, the concentration of the soluble carbon nano-tube suspension liquid is adjusted by adding the surface active agent deionized water, and the concentration of the soluble carbon nano-tube suspension liquid at the transmittance of 85 percent is determined by testing the limiter through low-energy density pulse laser; the prepared soluble carbon nano-tube suspension liquid is added into the transparent glassware, and a vacuum part of the glassware is vacuumized to minus 0.05MPa and then sealed. The low-concentration soluble carbon nano-tube suspension liquid limiter has the advantages and beneficial effects that the limiter is simple in structure, easy to prepare, low in cost, high in light limiting performance, high in transmittance for the laser at the low intensity and great in application potential on the aspect of the laser protection.
Description
technical field [0001] The invention belongs to the field of nonlinear optics, in particular to a low-concentration soluble carbon nanotube suspension limiter based on negative pressure effect. Background technique [0002] Since its appearance in 1960, laser has been widely used in the fields of medicine, measurement, chemistry, material processing and national defense due to its advantages of good monochromaticity and high collimation. Especially in the field of national defense, laser weapons are the most invested and fastest-growing applied research projects in various countries. Among all kinds of laser weapons, laser jamming and blinding weapons have been equipped in some western countries since the 1980s. The targets of such weapons are human eyes and photoelectric devices, such as interfering with or blinding the vision of photoelectric detection, artillery, navigation and guidance systems, and even human eyes. With the increasing number of high-power and short-pu...
