Description

Technical Field

[0001] The utility model belongs to the technical field of laser protective equipment, and in particular relates to an antimonene diaphragm type laser protective goggles. Background Art

[0002] Since its invention, lasers have been used in many fields. Lasers themselves have the characteristics of good unidirectionality and high energy. In laser use environments such as experiments and medical treatments, their high-energy light can cause damage to human eyes and optically sensitive devices in a short period of time. In order to cope with the potential risks of using lasers to humans and the permanent damage of laser weapons to humans, people have proposed the concept of laser protection. The laser protection system on the market uses bandpass filter devices as the main component, but it is not targeted at different incident laser intensities. In weak light conditions, effective signals are easily lost. Nonlinear optical devices can be used as laser protection, and they can have different transmittances for lasers with different incident intensities. That is, nonlinear optics as a means of laser protection has aroused people's interest. The application of visible light and near-infrared lasers is very broad, including communications, micro-processing, medical instruments and other applications. When using this laser, how to protect human eyes and detectors is also worth studying, that is, laser protection in this band has also become very important.

[0003] Chinese patent CN213581640U only needs to set an absorption layer and a hardening layer on the upper and lower surfaces of the substrate to protect against lasers with a wavelength of 385nm-560nm, but it cannot be used to protect against lasers with near-infrared wavelengths;

[0004] Chinese patent CN113265115B uses a chemical method to prepare a laser protection film. The dichloromethane used in the process is an irritating and toxic organic compound, and the operation is complicated. The nitrogen-aluminum co-doped hydrophobic carbon dots obtained by this method can be used to protect against 532nm lasers.

[0005] Therefore, how to provide an antimonene diaphragm laser protective goggles that can perform optical limiting behavior on lasers in the visible to near-infrared band at a certain intensity and provide good laser protection for lasers in this band is an urgent problem that needs to be solved by technical personnel in this field. Utility Model Content

[0009] Temples, which are movably connected to the edges of both sides of the frame;

It can absorb most of the high-intensity lasers and pass the low-intensity lasers, effectively protecting the eyes or detectors.

The glass lens is first cleaned with alcohol and placed in a growth epitaxial growth chamber. The lens 3 is formed on a glass substrate by molecular beam epitaxy at a growth temperature of 250°C, a source temperature of 660°C, and a beam rate of The growth time is 9-42min, and a 10mm-50nm few-layer antimonene film is deposited.

[0028] In other specific embodiments, the frame 1 includes a base frame 11 and a cover frame 12, the base frame 11 is a U-shaped structure, a continuous card slot is provided on the inner side wall of the base frame 11, a card slot is provided on the bottom wall of the cover frame 12, a limiting slot is provided on the top of the base frame 11, and protrusions are fixed at both ends of the bottom of the cover frame 12, and the protrusions and the limiting slots form a mortise and tenon structure 6.

[0032] When the incident intensity of the laser with a wavelength of 532nm and 1064nm is too large, it will cause optical limiting behavior to reduce the incident intensity of the laser and protect the detector or eyeball. Nonlinear absorption measurements are performed using lasers with a laser frequency of 10Hz, a laser pulse of 40ps, and a wavelength of 532nm and 1064nm.
