I finding a blue laser

Hello I would like a blue laser.

I've always had green or red lasers, not very powerful. up to 50mW, almost all purchased in China. DealExtreme and shops like ...

Before I find that blue lasers had high prices.
Focalprice want to buy because I have several discounts ..

I'd rather have AA / AAA. Power seems to me that had wanted to be powerful to see the beam. I have $ 25 cash

I you can recommend?
Apart red, green, violet, another color in the store FP?

Well, first off I wouldn't buy from focal price, but that's just me, you can get lasers from trusted members in the Buy Sell Trade area, then you know your laser will be up to spec, and good quality.

Secondly, I don't think you can get a 1W laser with standard 1.5v AA/AAA as they don't supply enough Amps, your going to have to go with 3.7V Li-ions.

As for what power you need to see the beam, I can easily see an 85mW 445nm (blue) beam at night.

Also, 25$ isn't going to be enough to buy a 445nm laser, you're probably going to need 200$ to buy one with batteries, more if you don't already have goggles.

The blue diode alone is ~$45

Hi thanks for your help
say you bought it 2nd hand in?

I am looking for a laser to 30-50nW not want it to be dangerous.
noooooo 1W :drool:
And using AA / AAA.

This is the most powerful Chinese laser I've ever played.

If you say so you can see the beam have to be 85mW, perhaps with a high price, buy something cheap and simple, if I get tired I throw in the trash.


Sorry for the mistakes, im spanish
regards

I made a very nice blue pen ~30mw for about $100

30-50mw of 445 blue costs the same as a 1W+ blue laser

And the 1W requires quite awesome (additional costs!) safety glasses. Better just buy the 30mW instead. Lots better value for the money

I assembled a list on http://laserpointerforums.com/f65/445nm-cheap-66633.html

Either that or purchase a built from a member here.

But I me cannot really vouch for cheap builds in any way

Here is one I made The pics are cell phone quality. It is about 30mw and 445nm. The problem is they all use the same diode so that cost is about the same no matter what.

Cost ~$100

Diode $45
Flex Drive $30
Pen Host $12
Switch $3
Aixiz Module $5
