Hi guys. I received my first laser a few days ago from a LPF member and I will dedicate this thread to it. I am going to a star party tonight at the Physics department at my university and they said they would help me measure the real output of it using some of their instruments. It says it...

I just got mine a few days ago, I will try to post some pics soon.

I went outside the other night and was practicing turning off street lights with my new optotronics 150mW but there were many military planes flying around so I stopped as soon as I saw them in the area. I guess thats what I get for living so close to a military airport :(

Re: FOR SALE 532nm GOGGLES Payment sent, Will these protect my eyes from a direct hit from a Optotronics 150mW?

Re: FOR SALE 532nm GOGGLES PM sent.

OK thanks, I think that makes sense to me now.

This happened a few days ago, you can read the comments to get the general public's reaction. Most of them dont think we should ban lasers altogether ( since anyone with a gun poses just as much a threat) but some of them are ridiculous. Link--> Spike in laser attacks - thestar.com

Is it this one? Optotronics Product Details One of my friends might be interested, ill tell him.

I just purchased my first green laser and it is on it's way now. It has an operating temperature of 15°C to 30°C ( 59F- 86F ) My question is why? I understand the diode can heat up and deform or break due to overheating but why is there a low temperature range as well? If we need to duty...

Welcome to LPF. I live in Manchester, TN ( Near Murfreesboro ). I was in Pigeon forge and Gatlinburg last weekend. Beautiful place. I bought a 160mW green Optotronics laser from a member here. Can't wait to test it out. Next time I come to the Smokies I'll bring it with me.

payment sent. Thanks!

yep, optotronics, I heard they are very good lasers for the price.

To the top..

I am wanting to buy a 150~200mW Green laser that has had little use and comes from a reputable dealer. Let me know what you got. I really like the Opto's btw.

Ill take it if its still available.

Does this have an IR filter? Will it damage my eyes if do not have eye goggles? I will send you a pm.

is there that big a difference from 125mw to say, 75mw? Id be willing to drop in power a little bit if I could still get something that would be under $100 and the beam could be seen in the day time. I'm still learning about green lasers to be honest though.
