How to use a laser pointer to draw, to write and to record it? I think it is a very interesting thing. With the help of a camera with the function which could set longer exposure time,you could easily record what you draw and write with the laser pointers.
This is a 300 mW handheld laser pointer with good power stability. It can last about 3 minutes at 300mW. Now this video is showing how to burn a balloon with it. I think it is very interesting and excellent.
This laser is made by CNI laser, China.
As I known earlier, the blu-ray laser diode is widely used in blue laser drive or player and its output power is usually from 5mW to 7mW of laser radiation at 404-407nm (nominally 405nm) in the violet part of the spectrum. Because it is at the violet end of the spectrum, it will not be as visible as blue, green, or yellow laser pointers, but the color is absolutely gorgeous, and is very radiant and unusual for a laser pointer and a portable laser.
This 405 nm laser pointer is made by CNI laser, China.
A simple video of CNI laser,I will study how to make video,then upload a better one.
