Lasers on Aliexpress.com

Another one for AliExpress, check out my "True 300mw Output" greenie bought over Xmas.

Yes the diode is so badly mounted at an angle that it bounces part of the beam off the metal insides of the collimating lens.

Oh and is 80mW tops. Yes I know the cat should probably be wearing safety goggles.

ohh what a shame... only 300mW. Mine's 50,000mW Muahahahaha :drool:

I don't know if he is kidding but there is no way your 532 is 50W's.

Hec, 1W of 532nm is hard enough to achieve and a lot of heat is released during the DPSS process! Not only is 1W already expensive, but 50W's would be something only laboratories/universities could afford

This is a good one too:

100W, 1000000mW (insert random large numbers here) heh.

But that's nothing compared to this one:

Yes that's right, a 50 gigawatt laaaaazer! I bet as soon as you turn it on it pokes a hole through the building and blinds everyone within a mile.

And all in a cheapy 301 host! Amazing what they can make in China

I'm not the one who's kidding. The people who list them on Ali Express are. Of course these can't be 50W.

Buying a laser off of Aliexpress from a China seller is ten times worse than on ebay, in my experience, you can expect to be ripped and never get what you pay for, not according to their descriptions. I am sure there are examples of good sellers, but for the things we want or the so called higher power ones, never what they say, 10 to 1 percent, or even less of what they say the power output is normal.
