Default Hello from Xinjiang, China

Hello everyone, I'm from Xinjiang autonomous region of China. This is my second post in this forum. Well my first post was about asking for help... My English is not so good. Hopefully you can understand it. I had been living in Australia for 5 years since 2008 and I moved back in June this year. The good thing is there's no ban on laser usage here in China, at least not now. In Australia lasers above certain mW are banned.

I like astronomy, photography, and now lasers. I got to know this forum just a month ago and I've learned a lot here. I just bought a PGL-III-C 500mW 532nm laser from CNI. It costs 3300RMB (around $540 ) here in my country. The laser looks good, very solid feel. The beam is very beautiful. In doors, the laser spot on the wall is too bright to be looked at without safety goggles. However my laser tends to show crazy mode hopping phenomenon. So next coming week I'll contact CNI and probably send it back for a replacement.

I've taken a video which shows the mode-hopping and output dropping of my CNI laser. You can watch it below here.

welcome, you'll fit in fine here. your english is very good, I understand it like you were a local.

check the first post of this thread. http://laserpointerforums.com/f55/cn...e-84942-8.html

it says the 1 piece price for a PGL_III-C 532nm is $280, so it seems something is wrong here. I was under the impression the 1 piece price quoted to the forum for the group buy was the price anyone can get, so your equivilant of $540 was possibly too much. I am not entirely sure on this.

Either way, your laser is defective I'd say. especially if you've tried it with different batteries that you know are good. It should not drop in power after such a short time, on a good battery.

Hopefully CNI has good customer support. I don't know much about it

Thank you!

About the price, yes CNI lasers are really highly priced here in my country. Jetlasers and Scitower are little cheaper than CNIs but still expensive for the majority. The 500mW 532nm PL-E Pro laser from Jetlasers is priced at 2400RMB here(~$395) and the 500mW 532nm SCT302 from Scitower is at 2600 (~$425). I wish I were in America. Everything is cheap! The new iPhone 5s only sells $200 in the U.S. but sells $1000 here in China.

Yes, I've tried it several times with 2 of my newly bought and fully recharged panasonic NCR18650B batteries (3400mh) and with an old fully recharged Sanyo 2600mh battery. They turned out the same.

Welcome to the forum!

It could be that the laser is broken, or was used before and then refurbished to you, so send it back definitely, when you get a new one test it right away, dont keep it on for too long, a diode might die

Thank you Krane for your advice!
I normally keep it on for one minute or shorter. For the tests, I kept my laser on for about two minutes as CNI told me not to keep it on over two minutes.
I'll contact CNI next week and see how they will deal with this.
