Value for money laser pointer
The high power laser pointer looks like a great value for money. I can say it works great and doesn't change after shooting. I almost forgot, another use of this site is astronomy. If you don't like astronomy, skip to the end. I tried to take a photo of the job at night and failed. I don't know if it's really 5000mW of fun, but it's really, really powerful. Mine has four settings: full power, half power, a little less power, and SOS, each of which is set by clicking the tail switch. The downside is that you have to cycle through all four every time you turn it on or off. No batteries either. A lifetime is typical.

How to improve the laser pointer?
The aerospace industry regularly replaces aircraft parts after they reach a certain number to avoid catastrophic failure, Patterson said. Replacement plans are based on the average performance of several identical components, not the actual performance of individual components. The SHG method can be used to verify whether a particular component is truly worn out or still has a useful life, saving time, money and materials.
Although the laser pointer is 60,000mw, the microscopic black hole does not live long. In 30 femtoseconds (one millionth of a millionth of a second), the molecule loses more than 50 electrons and then explodes. At laser temperatures of thousands of degrees, molecules have never stood as they do now. With the help of lasers, they can collect data from molecular samples in the blink of an eye, but the samples are inevitably damaged and destroyed. It wasn't always clear whether the scientists' measurements were from an unstained sample or something that reflected green laser pointer damage, Boot said by phone.
