    CNI no longer exporting >5mW?

    That's not entirely true. You can still have someone who lives outside the U.S. forward them to you.

    CNI no longer exporting >5mW?

    Has anyone else confirmed that CNI is no longer shipping to the States? I think someone else posted a similar topic a while ago, but it was proven to be false.

    Pioneer 16X BDR-209DBK

    Very impressive. I hope it won't be long before single-mode 445 nm and 520 nm diodes reach similar powers!

    Importing a laser module or laser diode to Australia.

    Customs doesn't have enough time to check every single package, so even regular lasers could still go through. Of course, this would be a gamble.

    100mW 532nm for $15

    Be careful. That user's feedback is only 83.3% positive.

    New Generation 445nm Diodes: Nichia NDB7A75

    I wonder when Soraa is coming out with their 4 W diodes?

    405 nm laser pen from eBay has irregular dot shape

    I figured that was the case. As the saying goes, you get what you pay for. :P

    405 nm laser pen from eBay has irregular dot shape

    I noticed the dot of my 405 nm laser from eBay has a very irregular shape - it's as if there is a large "solar prominence" sticking out of it. The camera I'm using doesn't capture the dot very well, but here is a rough picture: Does this mean the diode has defects, or is it normal?

    New Zealand Laser Law Change - DUE March 1st 2014

    I'm not surprised the law actually passed. Let's just hope it will not be strictly enforced.

    do 532 nm goggles offer protection against 405 nm lasers?

    So my 405 nm laser "pointer" from eBay just arrived yesterday. This unit seems to be one of the less powerful ones as it doesn't burn anything or even sting my skin, but it's probably still more than the advertised 5 mW judging by the brightness of the dot. If I had to guess, I'd say the output...

    How healthy are your batteries? (How to measure internal resistance)

    This is very useful information. Many years ago, I was wondering why one set of my batteries had normal voltage but gave poor performance when I put them in a laser. I think this thread explains everything!

    how to quickly tell if a laser has reverse polarity protection?

    Is there any quick and simple way to test if the driver of a laser has reverse polarity protection? I've heard one method is to run a very low reverse current through the driver and see if there is any flow, but I don't have any equipment that can generate such currents. I guess I could always...

    anyone ever buy from eBay user "demonerrr"?

    The laser just arrived today, and it seems to work fine. Woohoo! I hope to have a review up soon.

    anyone ever buy from eBay user "demonerrr"?

    Maybe a bit of bad news: the user's feedback has dropped from 98.4% to 98.2% over the past two weeks, and most of the complaints are from users that did not receive their item. I hope I won't be one of them. :O

    What camera(s) do you own?

    I use my trusty old Nikon Coolpix S550. It's a great camera; the only downside is that it doesn't do night shots very well.

    how long should I expect to wait for free shipping from Hong Kong?

    So I ordered a 405 nm laser from eBay on the 20th. As of this afternoon, it has not arrived yet. From what I gather, delivery times of up to two weeks are not uncommon if the if the item is shipped overseas. It's also the holiday season right now, so that will probably add at least a few days...

    safe to use Energizer e2 Lithium batteries in 405 nm eBay lasers?

    Are you saying the eBay lasers have a boost driver and can safely accept these voltages?
