Is it better if a wavelenght on a laser pointer is higher or lower?

The wavelength only reefers to the wave length of light in the visible light spectrum in. Basically what colour it will be. The Higher the number the deeper purple (violet) it will be. Too high it will be an ultra violet laser, which we can not see. The lower the number the deeper red it will be. Too low it will be infra-red, which we can not see with the naked eye as well.
The mW (milli-watts) is what determines if the laser is going to better. The Higher the mW, means the higher power output, which means, a brighter, better laser.
At any wavelength, and enough mW, all lasers are very dangerous. Ultra-violet and infra-red lasers burn and cause eye damage all the same as the visible light lasers.

What is the Wavelength of a red laser pointer?

How do you increase the power of a red laser pointer?
Well, I know how, but it's not a good idea as it will make the laser produce more ir radiation, which is not good for you at all. I recomend buying a new laser. techlasers.com is the best, i just bought the 125mW infiniti, and its amazing. Also,you can replace laser diodes inside the red laser pointer,laser diodes are available on freaklasers.com

If the room is dimmed slightly then any laser pointer will work, the higher end ones just work a little better when the lights are on.
Which is better a 5mw green laser pointer or a 5mw blue laser pointer?
Well I wouldn't say either one is better; it depends on what you want: If you want a visible beam / bright laser get the green one. green can do everything a blue can and more if its limited to 5mw but blue is just cool because its blue. its not better its just expensive I perfer green they can be quite cheap for the type of laser on Ebay. Blue always hangs cheapest around 50$ less if your lucky Blue is always expensive I dunno why but its not better if your comparing 5mw to 5mw, not in my opinion at least the green laser is better you can go all the way to 1000mw's witch is powerful don't go to eBay. you can find what you want on this site here ya go. happy hunting laserpointerpro.com have fun you will be on that page for awhile.
