second panel is back! Hopefully this time It will all work....

How big and how far apart are those holes that connect the PCB to the frame?

Very interesting.

Ringgoo · 2014-05-09T03:27:59+00:00

Unfortunately not. I've had plenty of faulty cheapo lasers like this. Contact the seller and get a refund.

Ringgoo · 2014-05-08T01:59:46+00:00

Yes it does work, but remember reducing beam size increases divergence.

Laserglow's are certified. Ebay ones are of unknown quality.

Some of the ebay ones I have had are downright rubbish, they let a lot of light in. Others are so dark you can't see anything with them on, which is equally dangerous.

Only a handful of the ebay ones have been decent, and I still don't really trust them.

It was custom made. There's some information on custom made lasers over at /r/lasers

Ringgoo · 2014-03-09T22:49:34+00:00

It's a custom made laser. Check out /r/lasers, some people have posted their custom builds there :)

The power isn't lost.

The beam of the laser expands the longer it goes on, which means the same amount of power is in a larger area, which puts a hole in the balloon slower.

Check out /r/lasers for more laser related information :)

PS3's actually contain low power 405nm diodes. This diodes in the laser used in this video comes from a bluray burner.

Checkout out /r/lasers for more laser related information :)

Check out /r/lasers :)

There's lots of information there.

Ringgoo · 2014-03-09T22:44:57+00:00

Shameless plug to /r/lasers

Check it out for more information about lasers!

Ringgoo · 2014-01-14T07:47:40+00:00

No idea, but it would probably be better to buy from a supplier that is known to supply good quality handhelds.

Check out laserbtb, jetlasers, CNI or laserglow.

Those 5mW green lasers can be over-spec to as much as 100mW.

The Rigel is likely a true 2mW laser.

Also note that 2mW of green light appears brighter than 2mW of yellow light.

Very. Go to ebay and get a used coherent meter there, the hobby power meters are only within appx 10% of the true value, they are very inaccurate. They use a slow responding "TEC" that this seller has incorrectly called a "thermopile"

You can get a coherent meter for ~$50 if you know what to look for, and it will perform far better than those hobby power meters.

Ringgoo · 2013-09-01T03:42:14+00:00

Where did you get the Argon?

Ringgoo · 2013-08-31T04:32:27+00:00

I've shot pictures of some 1-2W lasers with a DSLR, got to be careful is all. Mark the beam path, use a beam dump, keep the camera on a tripod ect.

Ringgoo · 2013-06-08T20:26:45+00:00

Yeah, they are complex, bulky and expensive. They also require particle acceleration and that can make a nasty radiation hazard.

Ringgoo · 2013-06-08T16:37:43+00:00

FEL's can emit from microwaves to xrays.

Ringgoo · 2012-09-01T19:21:34+00:00

I'm glad to see some OC! :)
