The invention discloses a preparation method of an AlGaN-based edge emitting laser cavity surface. According to the invention, a ridge is prepared by adopting dry etching, then an end face is prepared by adopting dry etching, two ends of the ridge respectively extend out of two ends of the end face, and two side walls of the ridge and two side walls of the end face covered by the ridge are located on the same plane; performing wet etching at room temperature to expose the end surface and the m surface of the ridge; and the wet etching rate is more easily and accurately controlled by the room-temperature wet etching, the m surface of the end surface with large width is more easily controlled to become smooth, and the side wall of the ridge on the same plane with the m surface of the end surface becomes smooth along with the smoothness of the m surface of the end surface and is used as a light-emitting surface, so that the thickness of the ridge is reduced at room temperature under the condition that a high-precision precise photoetching machine is not used. A vertical, smooth and damage-free resonant cavity surface can be obtained without a high-risk high-temperature etching process and complex process steps; the process design is simple, the production efficiency is greatly improved, and meanwhile the safety risk is reduced.

This application discloses a composite grinding sander, comprising: a housing; a motor disposed within the housing for providing driving force; a drive shaft connected to and driven by the motor; a connecting seat, one end of the drive shaft disposed within the connecting seat; a oscillating grinding disc disposed at the bottom of the connecting seat, having a grinding disc groove at its center, and connected to the drive shaft via an eccentric transmission mechanism, causing the oscillating grinding disc to oscillate when the drive shaft rotates; and a rotating grinding disc disposed within the grinding disc groove, connected to the drive shaft and capable of rotating with the drive shaft. High-speed rotary coarse grinding is achieved through the central rotating grinding disc, resulting in a high material removal rate; and oscillating fine polishing is achieved through the peripheral oscillating grinding disc, resulting in a smooth surface. Both work collaboratively in the same process, solving both the surface roughness problem of traditional rotary coarse grinding machines and the low efficiency problem of traditional oscillating sanders.

The invention discloses an intelligent simulation confrontation system and method based on laser coding and tactile feedback, and belongs to the technical field of electronic games and simulation training. The system is composed of an intelligent simulation gun, intelligent sensing clothes and an internet platform in a cooperative mode, and unification of safety and immersion is achieved through double-laser coding emission (light condensation / light diffusion), dynamic damage judgment, multiple sensory feedback (sound / light / force / electricity) and a state linkage mechanism. The innovation points comprise that the double laser modules are respectively adapted to far / short-range strike; the internet platform supports parameter configuration and state uploading; the dynamic damage algorithm is combined with weapon types, distance attenuation and protection levels; the immersion sense is enhanced through touch electric shock and acousto-optic feedback; and automatic forbidding and array prompting of the gun are realized through Bluetooth / wired linkage.
