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.

What can laser pointers do?
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.
What does nm mean on a laser pointer?
nm is nano-meters. There will be a number preceding the nm. This number indicates how many nano-meters for a full wave length of the laser light.
Where can one purchase a green laser pointer 100mw?
You can buy cheap laser pointers online. Here is the reason: There are thousands and thousands of people searching the web for brighter, more powerful, and cheaper lasers of all colors every single day. The internet can pretty much take all of the credit for allowing this global industry to grow so rapidly. When you can connect laser manufacturers from China and Japan to distributors in the United States, the UK, Canada, and Australia; you can expect loads of people to get their hands on powerful laser pointers. Then you can see more choice for you on the internet! http://www.dinodirect.com/Electronics

How are light bulbs relevant today?
We use them in many things, including but not excluding: cars, lamps, microwaves, spotlights, stadiums, laser pointers, computers, diving lanterns, and projectors. They are even seen on TV or in movies (light-bulb=idea)
What property of light does a laser show clearly?
now lasers can produce many different colors, as well as well as infrared and ultraviolet radiation.
How is a laser light different from a regular light?
laser light has a constant wavelength whereas regular light is made up of many wavelengths
What type of laser lighting is recommended for light shows?
There are many types of laser lighting that are recommended for light shows. Typically, laser scanners are the best type of laser lighting that is recommended for light shows.
How many lazer pointers does it take to cach stuff on fire?
It strictly depends on the strength and power of the laser pointer/s that you are using.
What other uses do lasers have?
Lasers have many uses, laser pointers, cd/dvd/blu-ray players and writers, Optical tweezers, Laser cooling, Communications, just to name a few.
What laser light like?
Laser rays are many light rays focused into a single light ray. That ray is a laser ray. The more lights rays focused into a single ray, the more powerful the laser ray.

Can we see microbes through laser light?
You don't need laser light. Normal light will do, for many microbes. You DO need a microscope, since they are way too small to be seen with the naked eye.
