powerful non burning laser
Hi,
When i was about ur age, I have such a crazy idea like u do.
After I graduate my Master degree in optical physics, I realize that your request is a bit funny.
Dude, you can't merge all the laser beam using a mag glass to burn paper. The laser pointer is only class 3, it dont have enough power to burn anything... not even a dust. Inside the pointer is a Laser LED that is not commercially available except in a laboratory equipment store. Until now, people already made several laser color such as IR, Red, Green, Gamma, Xray, and in recent years... blue. Blue laser can be found in a blue-ray DVD player. So, it is all monochromatic or one color. White is multi color. There is a white laser, it is called a dye laser. its the only laser can emits any color in the visible color spectrum.
Non visible laser such as IR, UV or X-Ray are the most powerful laser ever build. To burn paper, use IR laser that you can buy in lab equip store for around usd1000.
Keep your wild imagination kid, that's the sign of creativity.
