Some users may think that color is more important for burning ability, such as green, because it is the brightest Laser pointer color for the human eye in the visible spectrum at the same output power. However, this is a common misunderstanding. The most important factor of a high-power laser is the actual intensity of the beam itself, which has nothing to do with the actual color. Generally, the power of the laser that can light a match, pop a balloon or cut a tape must exceed 200mW or 300mW, the higher the power, the better. For example, a 3,000mW blue laser pointer will be a fast-acting burning laser tool, and a 200mW device will only be able to eject a black balloon. So remember that the higher the output power, the better this application.
Therefore, since we know that we need at least 100mW of power, and the higher the power, the better the combustion performance, we need to study different types of laser engraver. In general, AAA battery-powered pen or keychain lasers are almost never regarded as burning lasers. Many of them have power as low as 5mW, which means they will be visible and useful, but will not be able to light matches or pop balloons. Larger cells using rechargeable batteries make up almost all lasers that are classified as burning. Therefore, be sure to check the main body and battery of any single unit. If its pen is powered by AAA batteries, then it may not be a high-power burning laser.
Many handheld blue laser pointer use a fixed focused beam, which means you cannot change the width or intensity of the beam diameter. If your laser power is high, it is suitable for burning experiments, but using a pointer with a focus-adjustable lens will add more beam control and allow you to actually reduce the beam size and have a large impact on the target. Increase strength. Looking for a laser with focus adjustment options, you will usually turn to the left to expand the beam and reduce the heat intensity, then turn to the right to reduce the beam diameter and increase the burning capacity. This is essential for mW power units on the edge of the combustion limit.
