Most high-quality high-power handheld lasers do come with a pair of safety goggles included, however, if the one you’re considering does not (maybe look elsewhere), or simply add a pair of safety goggles to your order. It should go without saying but using a high-power laser, especially with the ability to burn, will require a bit more safety consideration than your everyday laser pen. This is critical for mW power units on the edge of the burning limit. Look for lasers that have a focus adjustment option, where you typically turn left to widen the beam and reduce the heat intensity and turn to the right to reduce the beam diameter and increase the burning ability. This is fine for burning experiments if your laser is high in power, but utilizing a pointer with a focusable adjustment lens will add much more beam control and allow you to actually increase the intensity by reducing the beam size and creating a great impact on your target. ![]() Many handheld lasers utilize a fixed focus beam meaning you cannot alter the width or the intensity of the beam diameter. The same applies to a match head, put some black magic marker on it to speed up burning times. You can even use a white balloon and use a black magic marker to draw a circular target which will actually change the way in which the heat and light is absorbed into the balloon’s rubber, making it possible to pop as if it were black altogether. An easy fix for this is of course going with a high class IV laser over 500mW, or simply using a black balloon. For instance, if you’re trying to pop a balloon that is white, it will actually reflect much of the beam and heat and direct it away from the balloon’s rubber, making it far more difficult if not impossible to pop at lower output powers. Popping a balloon with a lower power burning unit, like a 200mW laser pen, you’ll need to keep in mind the color of your target. This is an area that is very easy to confuse as well. So keep this in mind, the higher the output power the better for this sort of application. For example, a 3,000mW blue laser pointer will be a fast-acting burning laser tool whereas a 200mW unit will just be able to pop a black balloon. As a rule, a laser that can light a match, pop a balloon, or cut electrical tape, will need to be over 200mW or 300mW, and the higher the power the better. The most important factor for a high-power laser is the actual strength of the beam itself, regardless of the actual color. ![]() Some users may believe that the color is more important for burning ability, such as green because it’s the brightest laser color to the human eye in the visible light spectrum at the same output power.
