Some common questions about laser pointers
Low temperature will have a significant impact on the formal operation of the high powered laser pointer. In a cold environment, the emission of the laser beam is always very weak, dim and not bright when activated. After working continuously for 10 seconds (some laser pointers will be shorter in green), the brightness of the laser beam will return to normal. Blue laser is very popular among laser enthusiasts and professionals because of its attractive sapphire blue laser beam. Most blue laser pointers have high power, so some laser enthusiasts use powerful blue lasers for various combustion experiments. Pay attention to the following points when operating a high-power laser pointer.

Before activating the laser, make sure that the battery is installed correctly. When using a blue laser, always wear laser goggles. If the working time is too long, it may overheat and affect the service life of the laser tube. Do not use blue lasers in dusty and water vapor environments (except for some waterproof and dustproof lasers). Keep the laser out of the reach of children. Remove the battery when not in use and place it in the correct location. Many handheld lasers use fixed-focus beams, so the width and intensity of the beam diameter cannot be changed. High laser power is suitable for burning experiments, but the pointer with focusing lens can further enhance beam control, reduce beam size, and significantly affect the target to increase intensity. I can do it. .. Look for lasers with focus adjustment options. Normally, it rotates to the left to widen the beam and reduce the heat intensity, and rotates to the right to reduce the beam diameter and increase the burning capacity. This is important for mW power sources at the combustion limit.
