Where?! O_o Also, 30 mW is just about what I need. I suspect this one is less. But since I have no reference to compare to, I can't say. Also, I obviously wasn't talking of comparing different wavelength lasers. Only of the exact same wavelength.

Thank you!

Hi there. One more noob joining the forum. My first encounter with this forum was a good number of years back, more than 5, probably, when I got a notion that my life is not complete without a powerful laser, or even a rainbow set of ones. I managed to get rid of that idea because I had...

The reason I provided no link is that I bought it offline, it's noname, and the markings are useless: <1000 mW (I don't doubt it's less than 1000 mW!), class III (not IIIa or IIIb, just III). I doubt it's 50 mW, but I'll be happy if it's 20 and not 5 or even 1. Also, I understand you need a...

I just bought a [relatively] cheap 532 nm today. It's Chinese with no stated power rating to speak of. It draws 300 mA at 3 Volts, but that stat is of no use because it clearly has a linear current regulator inside (the current stays the same as voltage goes up beyond 3 V). I assume it's a 5 mW...

Understood. So a 10 mW 532 nm DPSS laser will have the same beam power as a 10 mW 520 nm laser, even though the former has much worse efficiency.

Another quick question: does the power rating (xx mW laser) specify beam (emitted) power, or power draw from the power source?

Interesting,thanks for the note. Don't like in what way? Will not function outside spec temps? Will become permanently non-functional if attempted to operate? Will become permanently non-functional if subjected to temps outside of specs even if never powered on?

Noted. I'm spoiled by the fact that most forums combine consecutive posts into one automatically nowadays. This forum is based on vBulletin and I know many forums using this same engine that do merge consecutive posts from the same author. But I digress; I'll keep this quirk in mind.

Thanks! And please don't get me wrong, but that automated translation is awful. :) You may want to find a different translation service. Just saying it for your information :)

Thank you :) And thanks for the purchase links. I was hoping to find something cheaper than 30+ pounds, but if that's what it takes to get a true 50 mW unit...

I'm from Ukraine. I'll take your guess as a compliment to my English skill, ha-ha :) I can see some 50 mW green lasers for 10-20 bucks. Is it reasonable to expect them to actually produce that power in this price range?

Thanks, appreciate your systemic approach to the problem. I'm certain there will be no legal problem: this is a closed area with a bunch of garages that only the owners of these garages have access to. Not to mention that the system won't be operated unattended - obviously I will turn it on...

It is on public property, sort of, which is why I cannot place any physical objects too far outside my garage gate. There is no law against casting light on the ground in my country, on the other hand. As for people - that is a valid concern, but not a problem in this case. And I think it should...

Thank you! I want to devise some kind of a parking guidance system, like landing lights on an airfield. I have a relatively narrow garage entrance and while I can now reliably enter it with no casualties (after a year of tears and suffering), I still find it difficult to align my car parallel...

Hi folks. New member here, barely know anything about lasers and especially about what's available and what costs how much, so please bear with me. I want a laser line module (or a point module with a line attachment) that would be visible outdoors during the day (or at least evening) in the...
