5mw green laser?

[itsmei]

Hi, i ordered a week ago this laser from odicforce: Compact 5mW Green Laser Module - ACC - Detailed item view - OdicForce Lasers Online Shop

I bought it so i could use this laser as a safe laser to use around indoors with out having to worry about my eyes. I currently use 1 CR2 battery which when fully powered is 3.6v. The specs show that this laser is driven at 3V, when i power it up it does look a lot brighter than a 5mw. I can see the laser's beam clearly on a clear night with no fog. I also have a 5mw red laser and it looks a LOT less brighter than the green. Yes i know that our eyes are 50 times more sensitive to green than red's. Do you think that this is a 5mw or am i over powering it? Should the driver limit the voltage though? Is it safe to use around the home? How many mW does a green laser which you can see the beam clearly on a clear sky?

If you want pictures then just ask

Thanks

Sounds normal to me! A 5mw green will have a beam as visible as a 200mw red beam. You're eyes are THAT much more sensitive

I have a laserglow technologies 5mw green and it is perfectly to spec, and just as bright as you describe.

Ahh ok thanks, as it is so bright does it damage the eyes?

<5mW (Class IIIb) is figured to be "eye safe" as the blink reflex is quick enough to prevent any damage.
For general pointing etc. there is nothing you should worry about.

Also, I would say that 200mW of ~655nm is about equal to 20mW of 532nm.
