High-reliability anti-shock small-sized YAG laser

Abstract

The invention relates to a high-reliability anti-shock small-sized YAG laser. The laser comprises a shell, an upper cover and a laser cavity, wherein the laser cavity is a cylinder and is positioned in the shell; the laser cavity comprises a barrel body, a laser crystal rod, a xenon lamp, a rod sleeve, a rod support, a cavity mirror, an outer mirror frame and a wire outlet hole; the laser crystalrod is located on the center line of the laser cavity barrel body; the rod support, the cavity mirror and the outer mirror frame are arranged from the central point of the laser cavity barrel body tothe two ports in the two ends of the barrel body in sequence; the xenon lamp is connected with a trigger circuit located on the other side of an inner partition layer of the shell; and the trigger circuit is electrically connected with the power supply. When the laser cavity is designed, high acceleration vibration and impact stability brought by small size and portability are taken into consideration, the overall mechanical properties of the laser cavity, the internal reflection cavity and other fixed features are directly made into a whole, so that the shortcomings of frangibility and easy secondary damage caused by the traditional external cavity type, cavity and shell separation, and a condition that inner reflection adopts a glass substrate mirror surface reflection cavity can be avoided; and by reducing the size, the reliability of the laser, and the stability and weather resistance of the system are greatly improved.

Description

technical field [0001] The invention belongs to the field of optical precision mechanical design, in particular to the technical field of lasers, in particular to a high-reliability shock-resistant small YAG laser. Background technique [0002] Since the birth of the first laser in human history, the ruby ​​laser, in the 1960s, lasers have changed people's lives all the time. Whether in the field of communication or in factory processing, he is inseparable. In recent years, unmanned driving technology has become hot, and automotive sensors and sensor applications have emerged in an endless stream. Without a distance parameter, autonomous driving is useless. Laser range finders will play a greater role not only in unmanned driving, but also in some special occasions, such as military weapons such as drones and tanks. [0003] Now laser range finders are moving towards miniaturization and high reliability. On various vehicles, there are inevitably high temperature, high humi...

AI Technical Summary

Problems solved by technology

[0003] Now laser range finders are moving towards miniaturization and high reliability. On various vehicles, there are inevitably high temperature, high humidity and some relatively complicated vibration conditions. From a system point of view, the traditional " The concept of "complement" or "addition" is no longer suitable for this extreme design, because more and more potential problems cannot be completely complemented, and the more parts are separated in the whole structure, the lower the final product of reliability will be.
