Yesterday, I saw a video at youtube, after I clicked into the link posted behind the video, it is described as " the world's most powerful laser pointer"! Is it reliable?I'm not sure,but I saw an article before,it said that one of a laser pointer of wicked lasers have keep the world record of the most powerful handheld laser! BTW, If a laser's power comes to 30W , what things it can do?

Nope. Not even close to the strongest laser pointer. Wicked lasers was never, and never will be the strongest either.

You're also not likey to find a handheld laser pointer over 7W. Not likely anyways.

I am afraid not. Divide the power by 10 and it would be more accurate. But by no means is this a toy. It is a very powerful Class IV still by the looks of its burning capabilities. Based on the 2x 16340 batteries, it's ability to melt solder and burn through multiple CD cases, it is in the region of 2.5-3W. I don't particularly like the advertisement on the site, or the lack of safety goggles in the video.

With 30000mW( 30W ) output power and adjustable focus, this laser can light matches or cigarettes, burn paper and repel birds freely.

Repel birds freely? :thinking::tsk:
it will surely bring you a lot entertainment both at outdoor and indoor activities!

It will do that alright. Not a good thing.

Wicked Lasers, make quality hosts, but they definitely do not have the strongest lasers. 30000mw? probably a typo. more like 3000. Most of their lasers are underspec as well. You are much better off getting a good high power laser from Sanwu, or Jetlasers. They have much better quality, and are usually overspec. Or you can try your hand at building your own.

Not a typo, they have stated in brackets that they mean 30W. More like misleading specifications. Good advice by mentioning Sanwu though. The most important thing is what goggles do you/will you own Jastin?

Anything over 7W is going to have to be custom, at least for the moment.

Can't overstate this enough really. Even at 3W (3000mW), that's still 600x the "safe" limit (Safe being where your blink reflex will protect you). One accident with that much power and you suffer permanent vision loss, it could be a small spot or it could end up covering a large part of your FoV.

"Repel birds freely" :crackup: Go up to 30W and you could burn the feathers off the back of a crow from 100 yards. :crackup:. Not condoning animal cruelty of course, don't try that. Same rules apply to animals that apply to humans when it comes to lasers.

Curtis is right, that sort of power isn't something to be used for mere entertainment, safety must always be practiced. Goggles are an important part of that.

"Repel birds freely"

Crows can see 460nm very well I found out one day, some were tearing at a garbage bag in my back yard and I just flashed the beam a few feet over the can and they flew away scared and never came back. Wouldn't want to hit them with it though. They must have good vision to that wavelength, more than I do anyway to scare them so much in the daytime.

Interesting. It is known that certain insects are more accustomed to lower visible and UV radiation. I wonder if the short range allows for better optical focusing, hence better eyesight?

True Colors: How Birds See the World - National Wildlife Federation

Birds and UV Light: The Eyes Have It

How do birds detect ultraviolet (UV) light? To answer this question you must understand avian eye structure. The human retina has three kinds of cone cells (receptors used for color vision): red, green and blue. By contrast, birds active during the day have four kinds, including one that’s specifically sensitive to UV wavelengths. There’s another difference: In birds, each cone cell contains a tiny drop of colored oil that human cells lack. The oil drop functions much like a filter on a camera lens. The result is that birds not only see UV light, they are much better than humans at detecting differences between two similar colors.

What does the world look like to a bird with UV vision? “We can’t imagine,” says Auburn University ornithologist Geoffrey Hill. Since birds can detect more colors than humans can, scenes may appear more varied. And colors that already are bright to human eyes are—if amplified by UV reflectance—probably even brighter to birds.

This is good info. Thanks for answering my question. Wow, imagine being able to see wavelength difference even clearer than we currently can. :drool:

My bet is 405nm

Yes indeed, it's 405nm and I found out by accident while playing around with my 405nm ebay pen.

Please note, never point any laser directly at an animal or human.
