What kind of laser pointer is the most powerful?
If the strong green high power laser pointer cannot eliminate the danger, it is forbidden to sell the product in Germany. This applies to all laser pointers with a power higher than 1mW, that is, 3R to 4 levels. Just like this, which lasers are the most powerful? physics. -At Lawrence Livermore National Laboratory not far from San Francisco, there is the world's most powerful laser: "National Ignition Device", or NIF for short. Just like that, how far can the green laser go? The laser pointers you buy come in many colors, each of which has a different purpose. The color of the spot or beam of the laser pointer directly corresponds to the wavelength it emits. Although red lasers are most commonly used in homes, blue and green laser pointers are becoming more and more popular. You can choose a variety of colors, ranging from 532nm green to 450nm blue, 405nm purple and 650nm red.

LiDAR (Laser Detection and Measurement) is an important part of almost all driving assistance systems (except Tesla). Systems such as emergency braking and lane assist in semi-automatic or autonomous vehicles use lidar to calculate distance. This is because the LiDAR system can emit very short astronomical green laser pulses. When the laser pulse hits an object or person, the laser is reflected by the detector and captured. The time required for a laser pulse to strike an object or body and be reflected is very short, and can be used to calculate the distance from the device to the object. The assisted or autonomous driving safety system can then decide whether the vehicle should brake, slow down, or bypass people or objects.
