Blasting the brain with a high powered laser is a booming technology in the field of neuroscience. A postdoctoral researcher fires lasers at the brains of mice every day for medical research. However, he is also very aware that the continued existence of high-power lasers can cause significant damage to the brain. You are unlikely to put the laser pointer on the side where you are sitting and come back. Suddenly, it didn't work. If so, then it may be a battery. However, if your laser pointer stops working for other reasons, it is most likely due to hitting another surface (you dropped or hit it). When it comes to high power output, it is always important to add an internal cooling system. The internal metal heat sink can properly maintain the stability of the portable laser by continuously increasing the temperature during operation. With this thermally stable design, the Pro 1000mW series high-power green laser pointer can maintain an ultra-long life of more than 8000 hours. It is not recommended to point this high-power green laser for more than 30 seconds. Reasonable operation can always ensure that the laser is in the best condition and prolong the life expectancy.
With the further increase of laser power, the risk of eye injury also increases. Even flashes are of no avail. A powerful hand-held laser can burst balloons, light cigarettes, and cause immediate damage to the eyes at close range. It may not cause minor eye damage to the pilot of the aircraft. The pilot’s eyes are farther apart (laser beams do not travel with distance, so not all light enters the pilot’s pupils).
