1. Laser hazards

                           Direct laser radiation: Causes permanent damage to vision or even blindness, causes burns to skin, and can 

                           easily ignite combustible materials (paper, plastic, wood) and cause fires.

                           2. Safety protection

                           A. Wear goggles and never look directly at the laser source or the laser reflected from any surface.

                           B. Be sure to keep all optical components below eye level, paying special attention to the height of your eyes 

                           when sitting on a chair.

                           C. The beam is not allowed to leave the optical table - such as changing to a vertical or tilted direction.

                           D. Avoid operating the laser in a dark environment.

                           E. A shield should be installed at the end of the light path to avoid direct exposure to people or smooth metal 

                           surfaces or walls.

                           3. Safety regulations

                           A. Lasers must be trained on safe use of lasers before they can be used, and no unauthorized use is allowed.

                           B. It is absolutely not allowed to use optical instruments to directly observe the direct or specular reflected 

                           light of the laser.

                           C. Indoor personnel exposed to lasers should wear qualified professional protective glasses. When bending 

                           over the laser table, be sure to protect your eyes to prevent radiation or direct exposure. Before using the laser, 

                           try to remove watches, rings and other reflective items to prevent damage caused by laser reflection.

                           D. The laser beam should not be at the same level as the human eye and should be limited to the experimental 

                           bench as much as possible; the laser should be enclosed as much as possible. The laser beam should not leak 

                           outside except close to the target; the laser beam should be kept away from combustible materials.  

                           E. The walls of the laser laboratory cannot be painted black. It is best to use light-colored and diffuse paint to 

                           reduce mirror reflection. The brightness of the room should be increased as much as possible to narrow the pupils.

                           F. Obstacles should be set up to prevent irrelevant personnel from approaching the laser. High-power lasers 

                           should have safety warning signs when working.

                           G. A "Beware of Laser" safety sign should be set up at the entrance of the laser laboratory.

                           H. The optical path will be terminated after the laser is used. Personnel must be on duty during laser work. 

                           When turning on the laser, strictly follow the operating procedures for water, electricity, and gas.
