I would contact your local laser surgury center for more information. They would be the best to talk to regaurding your questions. Also they would be more reputable.
A good start to learn about lasers is to visit Wikipedia and read their article on lasers, their conception, and their mechanics. To find out more, scroll to the bottom of the article and click on the sources Wikipedia used to make their article to find more detailed and professional sources.
Just go to Ebay and search green lasers and you'll get some results

Industrial lasers are built to be more rugged and easier to maintain.
Laserbtb is a website that exclusively sells lasers, including 50mW green lasers, as well as safety equipment to wear when using lasers. Lasers can also be found on Amazon, and eBay as well.

Blue lasers are preferable to red lasers primarily due to their shorter wavelength, which allows them to focus more tightly and produce higher resolution images. This characteristic makes blue lasers particularly advantageous in applications like optical storage (e.g., Blu-ray discs) and high-definition displays. Additionally, blue lasers can emit more light energy, resulting in brighter outputs compared to red lasers.
532 nm lasers can be found on amazon, apart from that a great place to find these green lasers is places that deal specifically with astronomy. These type of lasers are used for pointing out stars and are actually forbidden in quite a few locations as dangerous.
Rotating lasers on sale can be found at Engineer Supply, Amazon, eBay, Red Back Lasers, Merchant Circle, Hultafors, Speedy Services, Lowes and Home Depot.
You need to be more specific with your question.
Lasers have evolved over time in terms of increased power and precision, allowing for applications in various fields such as medicine, communication, and manufacturing. Advances in technology have led to the development of new types of lasers, such as fiber lasers and diode lasers, which are more efficient and versatile. Additionally, the miniaturization of lasers has enabled their integration into devices such as smartphones and laptops.
well some lasers can burn and some cannot. and some that cannot are more powerful than others
