Abstract

The invention relates to laser light transmission equipment comprising a laser, a power supply, a light path and a laser identification and authentication unit, wherein the laser is respectively connected with the power supply and the light path, is used for outputting a power authentication code to the power supply, and controls the laser light to be output to the light path according to the power supply; the power supply is used for receiving the power authentication code of the laser, authenticates the laser, controls current which is output to the laser, and ensures the laser to transmit laser light; the light path is used for laser transmission in the equipment; and the laser identification and authentication unit is used for receiving the authentication code corresponding to the laser light from the light path, determining that the authentication code is matched with the laser identification and authentication unit and adjusting the current which is output to the laser from the power supply. The invention ensures that the laser can realize high-power output only when the laser is arranged in the equipment matched with the laser and prevents the laser light with high-power output from being transmitted towards open space randomly.

Description

technical field [0001] The present invention relates to the technical field of lasers, and more particularly, the present invention relates to a device and method for controlling laser emission with security identification. Background technique [0002] The safe use of lasers has always been a concern of people. In order to prevent lasers from harming the human body, laser protective devices, such as protective glasses, are often used in laboratories. However, the problem of preventing people from intentionally using lasers to cause harm has been difficult to solve, especially if such lasers are small in size and high in output power, they are more likely to be held and cause injuries, and the problem becomes even more serious. For example, high-power and small-volume semiconductor lasers in laser emitting devices such as laser display devices and laser scanning devices, anyone can properly purchase these laser emitting systems and take out the semiconductor lasers separatel...
