Got a green laser pen which I do not like.

My friend lend me a laser marked <5000mw running on 18650 which I find it very powerful (can see the beam all the way).

I am not trying to get a green laser which can allow me to see the beam all the way. Does a 200mw beam be more visible than a 100mw beam? I am thinking whether to get a 100mw or 200m or higher, just like my friend laser. Any help will be appreciated.

You don't NEED any....
What you do NEED is appropriate Laser Safety Goggles/Glasses
if you are planning to buy a High Powered Laser...

BTW... I am 100% sure that your friends Laser is NOT 5000mW.

Take a look at this lasers:

LZCB - CYBER 532nm 100mW Focusable Green Laser Pointer

LZSK - Stick 532nm 200mW High Power DPSS Green Laser Pointer

LZCR - 532nm 200mW High Power DPSS Green Laser Pointer

And remember to buy a power certification. If you don't think it is necessary now you probably will later when you wan't to know the exact power of your laser.

If you have $200 to spend i would take a look at this laser:

Crown upgrade 400mW green laser torch/adjustable/waterproof [OL-CGL-400] - $195.99 : Zen Cart!, The Art of E-commerce

I have seen many people buying this and getting about 400-600mW output, and remember to take in mind that it is waterproof (that reduces the power by ~ 25%). So great value for the price!

Thanks sjesper

Anyone know what is the minimum power of my friend laser? Indoor with light I can see a faint beam. At night the beam is visible from laser to as far as I can see.

The stronger the more visible it will be, but the more dangerous it will be.

Is it focusable and how good is it at burning - can it light matches, pop ballons and so on?

The only way to know the output of a Laser is
with a calibrated Laser Power Meter...

BTW... if he turns it OFF the minimum power will be 0mW...
