They are changed by a lens in the light machine, They have a white bulb and change the slides to pass through the tiny holes to make it seem as if it was a laser.
Laser
A prism will split light into its component colors. If a colored light is used, there will be less colors in the split light. A beam from a red light for instance will have very little blue or green light in it so you will not get the full spectrum from the prism.

No. There are laser pointers that are available to the public, but they are not weapons. Laser guns as you see in science fiction do not exist.
Lasers come in a variety of colors.
Laser lighting effects at a rock concert are not generally considered to be laser shows, rather visual lighting effects. That said, many rock bands use laser lights as part of their concert performance. Concerts in 2013 either known to incorporate lasers or anticipated to use lasers as part of their lighting effects include artists ranging from Daughtry and Three Doors Down to Justin Bieber to B.B. King to the Black Sabbath Reunion Tour.

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.
Colors are determined by the wavelengths but all wavelengths travel at the same speed. So no, colors do not affect the velocity of light.
Typically they come in green, red, yellow, blue or purple. The least expensive ones feature red lights and the most common ones feature green ligths.
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.
