Lit up 30 years ago the laser diode is the basis of all of the world's cheap lasers.
A ruby laser (depicted earlier) is a solid-state laser and emits at a wavelength of 694 nm. Other lasing mediums can be selected based on the desired emission wavelength (see table below), power needed, and pulse duration. Some lasers are very powerful, such as the CO2 laser, which can cut through steel. The reason that the CO2 laser is so dangerous is because it emits laser light in the infrared and microwave region of the spectrum. Infrared radiation is heat, and this laser basically melts through whatever it is focused upon. Other lasers, such as diode lasers, are very weak and are used in today's pocket laser pointers. These lasers typically emit a red beam of light that has a wavelength between 630 nm and 680 nm. Lasers are utilized in industry and research to do many things, including using intense laser light to excite other molecules to observe what happens to them.

Why do many laser pointers produce a red light?
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.
How strong does a laser pointer need to be to cut paper?
Burning paper requires 1 watt (1000 mW), which is more than what most laser pointers can achieve without modifications For comparison: Popping balloons or lighting matches requires roughly 100 mW (which is the high end mW range of most commonly found laser pointers) Note: laser pointers anywhere near 100 mW and up are very dangerous to the eyes and can cause permanent degrading of vision (some doctors say any laser above 5 mW can cause eye damage), so use with caution and never point at anyone's face
Where can one purchase a green laser pointer 100mw?

What are the manufacturing costs of laser pointer components?
The most important laser pointer components is the laser module . The costs for different colors of laser are different , about 1$ for red laser , 10$ for green laser and 200$ for blue laser . And the costs are keep going down.
Are laser pointers as bad as laser pens?
Laser pointers and laser pens are basically the same thing. A laser pen is a laser pointer with a pen attached.
Are gamma rays used in laser pointers?
no , laser pointers emit a lower wavelength of radiation
Why laser mouse are used?
Because the laser pointers are much easier to use than the ball pointers. The ball pointers are often difficult to move around while the laser pointers can move in any direction without "getting stuck"
How often do people buy a laser pointer in this world?
Laser pointers are often very useful. People purchase laser pointers for business purposes and in order to play with animals. They can be very entertaining for cats. People purchase laser pointers as often as they need them.
Is there a green laser pointer for 10 dollars?
You cannot purchase new green laser pointers for $10. Most of the green laser pointers for go around $30.
Is a laser pointer a ruby laser?
Not usually. Laser pointers are usually diode lasers.
What colors do laser pointers come in?
Laser pointers are available in red, blue, green, yellow, and violet (purple). Green laser pointers are the most preferred of all the colors because they are the brightest, most visible, and can be seen the farthest distances.
Can laser pointers get you kicked out of school?
