Have you seen big cats laser pointer?

Laser pointer injuries mainly involve photothermal damage to the eye, particularly the retina, which receives light through the lens, converts it into nerve signals and transmits those signals to the brain. Most laser designators are tuned to a power output of 1 mW, which is relatively harmless in most cases. The radiation output of the laser damage tested ranges from less than 5 mW to more than 1000 mW. These high-efficiency lasers typically emit light in the green spectrum, which, unlike red lasers, occurs at different wavelengths, including invisible infrared radiation. The shorter the wavelength of green light, the more obvious the photothermal damage. In one study, 90% of green laser pointer tested had an output power greater than 5 mW, the threshold for "high-power" lasers.

Laser Pointers could have been used to point at buildings and attract attention as a means of peaceful expression. He also observed that his client had co-operated with police during the investigation and that there was no evidence that he had ever used the device. He added that the magistrate ignored the possibility that the umbrella and alpenstock were damaged, rather than deliberately altered to harm others. But Pan concluded that the magistrate had the right and the right to draw those conclusions, especially when the accused did not testify in his defence and presented evidence that could weaken or defeat the prosecution. A 5000mW green laser can be achieved, but it is usually not pen-shaped. Some 5W 532nm/520nm lasers on the market cost thousands of dollars. Therefore, they are commonly used in scientific experiments, long-range positioning, airport bird control systems and other specialized fields. If you need a 5000mW green high powered laser pointer, its large size makes it difficult to achieve optimal stability. Before you buy, you need to choose different power for different purposes.
