The laser pointer mW intensity is the only significant factor affecting the beam's ability to burn. You need at least 300mW of power to do things like light a match, pop a balloon, light a fuse, etc. Most of the current laser pointers are red, green and blue. They are small but always expensive. The red laser pointer is relatively easy to make, the wavelength is about 600 nanometers, the technology is mature, and the semiconductor process materials are mature. The high power laser pointer wavelength is about 530 nm. At present, the semiconductor laser technology in this frequency band is not very mature. Therefore, green laser pointers are expensive and low-power. As a general rule, you need at least 200mW to light matches and pop balloons, but the higher the power, the better the burning ability. Class IV lasers are the most ideal burning capability as they are all 500mW or higher. Class III may be suitable, but only for the upper end of the power spectrum (200mW - 499mW).
Laser weapons experience 50 years of technological development
Today, laser weapons have experienced more than 50 years of technological development, and have made significant progress in equipment miniaturization, increased launch power, and rapid energy supply. Some tactical laser weapons can even serve as additional inputs to existing equipment systems. In practical applications, it has shown great potential and effectiveness in counter-terrorism, special operations and close-range maritime defense. 5000mW green lasers are available, but generally not pen-shaped. Some 5W 532nm/520nm lasers on the market sell for thousands of dollars and are generally used in scientific experiments, ultra-long-distance positioning, airport bird repelling systems and other professional fields. If you need a 5000mW green laser pointer, it's very large and difficult to stabilize. Before buying, you need to choose different power according to different purposes.
When you receive the driver, it must be set to the correct output. It's small, and it's a bit of a challenge to do that. But once you set it up, you'll be happy. Instructions are provided with the driver. Before this hospital incident, there had never been such a serious eye injury from a laser pointer. Aside from these formal uses when red or green low power blue laser pointer are used as play aids for cats or dogs, laser pointers should no longer be toys. Parents should encourage children under 16 to keep their distance from laser pointers. Anyone working on this optical device should always be held accountable. After setting up the driver, you need to solder the two wires from the old LED driver to the new laser driver. Once they are in place, you are done with the "pills".
