Advances in laser diode technology have produced an increasing number of laser pointers with high output power and more available wavelengths. The low-power green laser pointer is easy to see in daylight and is considered an ideal gadget for lectures, presentations, star and research, formal laboratory experiments, etc. during school or conferences. This gives people on the ground more time to use the laser on a single charge. This is essential for completing tasks or exercises. The 200mW green high power laser pointer beam is 5 times brighter than the 200mW red beam and 7 times brighter than the 200mW purple laser. This is what the military considers when choosing the right model for any actual training or exercise. Some people entertain their pets with different games, but when you get home tired from a busy day, tossing around with toys may not sound like a very exciting activity. That's when lasers come in: you can move a simple pointer while resting on the couch, or seek high-tech solutions, or even play laser games with your pet from a distance using your smartphone. Cats may be too lazy to play with their old-school physical toys, but they almost never refuse red dots.
Correctly identify laser products
In order to allow users to identify the danger level of laser products, we can classify laser products according to the mechanism of damage caused by laser products to the human body and the degree of damage caused. The wavelength and power of the laser product determine the damage of the laser to different tissues of the human body. The wavelength determines the absorption characteristics and damage mechanism of the laser. The power is related to the degree of laser damage. They are like business cards for blue laser pointer products, representing the degree of damage to laser products that users must pay attention to. We need a laser housing with a lot of power. I've seen flashlights used online. The one I use here is the one I bought from htpow in China. Laser diodes can be found on e-bay, here I made two pointers. A small controller is required to connect the battery. Just to remove all the small parts somehow, I just scraped them off carefully with a small knife. Next, you need to find out where to find the power supply. Just search with a multimeter until you find one point that connects to the ring around the controller and another that connects to the "button" below, then solder two short wires to them.
