What kind of laser pointer can cause ignition?
Many handheld lasers use a fixed focused beam, so the width and intensity of the beam diameter cannot be changed. This is great for burning experiments with high laser power, but using pointers with adjustable lenses can significantly improve beam control, reduce beam size, and have a significant impact on the target. In fact, the intensity can be increased by giving. .. Look for lasers with focus adjustment options. Normally, turn to the left to widen the beam and reduce the heat intensity, and turn to the right to reduce the beam diameter and increase the burning capacity. This is important for mW power units on the edge of the combustion limit.

In addition to visible light, some Green laser pointer also emit infrared infrared (IR) light. For example, the recommended laser pointer tested by the US government agency emits a slightly visible green light when outputting 20mW IR (four times the US legal limit).
