High-power lasers arranged in parallel
In order to see the laser "spot" on the wall or surface indoors or under dim light, a 5mw high power laser pointer is enough. The most demanding general-purpose pointing applications are pointing objects in bright sunlight, such as a tour of a city building during the day, and pointing stars at night when you need to see a beam of light in mid-air. For these purposes, 5-25 mW should be no problem, and for harsh conditions (high ambient light brightness, showing stars to a large group of people) the maximum is 50 mW. Whether a lighting technology can be widely used and its own technology research and development schedule and cost level. The successful application speed of single-channel parallel optical interconnection, with its extremely high cost performance, gives a large number of applications in broadband Ethernet and high-speed data communication networks; it is compatible with light-emitting diodes (LED) and is the most attractive for low-cost mass production Powerful manufacturing process.

Light Source
High-end cars have been equipped with LED headlights, and green laser pointer headlights have begun to be used, and some low-end cars are still dominated by halogen bulbs, and the yellow light of halogen lamps permeates in rainy and foggy weather. Xenon lamps use arc discharge to emit light. Compared with halogen yellow lamps, white people emit light. However, "high light dogs" use this type of lamp more, so the safety hazard is relatively large. The integration of two-dimensional arrays achieves higher power output, and because multiple high-power lasers can be arranged in parallel in the direction perpendicular to the substrate, it is very suitable for applications such as parallel optical transmission and parallel optical interconnection.
