because they are
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.
No, but the blue lasers recognize DVDs
As gemstones, abrasives, and in lasers.
Rotating lasers on sale can be found at Engineer Supply, Amazon, eBay, Red Back Lasers, Merchant Circle, Hultafors, Speedy Services, Lowes and Home Depot.
Rosacea can be an irritating condition to have, causing your skin to become red and irritated, but it can be treated with lasers. The pulsed dye laser (PDL) has been proven to show improvements in every patient. Other laser treatments include diode lasers, KTP lasers, CO2 lasers, Nd:YAG lasers.
no, it depends on the wavelength
Because the red ruby laser is the cheapest. Green lasers are usually more expensive. And the blue lasers found in blu-ray players are even more expensive.
Infra-red by itself is not dangerous at all. It is around us everyday. But I am sure that you are actually curious about infra-red LASERS. If shined into the eyes, IR Lasers can burn and permanently damage the retinas.
Green is the most powerful, next is red, then blue.
do you mean how far does the light go? red lasers can reach up to 10ft (at least as far as I've seen). at 5mw green lasers can range from (3000ft - 5000ft and still see beam clearly). at 5mw
It is the place where the red lasers are. You're supposed to have special glasses.
