    Which O-Like 445nm to choose? 1W blue or 400mW green?

    These are a few of the questions I find myself asking as I try and choose which of these Johnsons to purchase! I will also be purchasing the appropriate safety glasses along with whatever laser I buy. So I originally was stuck between the "Power Rock 1W Blue laser torch /Focusable/ waterproof...

    My new O-Like 100Mw red no different than the Amazon 5mW!

    About 2 weeks ago, I made the mistake of ordering a red 100mW cheap laser from Olike for about $11.99 or so, because like 2 days later, I read about that 3 laser value pack from Amazon for $26, with a red, green and violet laser, all of which are supposed to be way over spec. So I get the 3 pack...

    Why do we buy lasers, will we get bored with them quickly?

    I dont mean that thread title to start an argument or to upset anyone. Not at all. My concern is: What do you do with your new laser(s) to keep yourself from getting bored, so that the purchase didnt seem too frivolous? Here's why I ask this question: I'd always been into gemstones since I was...

    How much difference should I see between my 30mW 532nm, vs a 200mW 532nm?

    ***Noob question alert*** What I'm getting at here, is that I'm now considering buying an O-Like 200mW green(532nm) laser. Probably the "Power Rock", and maybe it's the "Cute" one, I'm not sure...(Whats with these names?) But it says Power rock. I've had my 20-30mW 532nm laser for 5 days now...

    How much power does a laser need before you feel heat on your skin from it?

    As mentioned 2 days ago, I now have the Amazon laser 3 pack, including: 1. 405nm laser of estimated 30-40mW or so(estimated by members here in reviews). 2. 532nm laser estimated at 20-30mW here 3. 650nm laser estimated at <>100mW Now I know that divergence will play a role in this, so I've...

    Duty cycles: How long on average? What if not listed?

    I was just outside checking out my new 532nm green amazon.com laser(it's the 3 pack for $26.99, 405nm, 532nm, 605nm). While showing it to my roommate, I would click it on for maybe 5-10-15 seconds at a time, then off for 5-10 seconds, then back on again. I did this for about 8 minutes or so...

    Anyone else bought the Amazon.com 3 laser value pack?

    This will not be a full review or anything, as I dont want to insult anyone with my 1.5 weeks of laser experience, then doing reviews! My right click button has stopped working on my laptop, even though it only has about 6 months of usage on it. So I cant copy and paste links til I get a mouse...

    How quickly do laser beams lose their power as they travel?

    When looking into safety issues and safety goggles, I read that a laser beam that hits you directly in the eye from close range might damage your eye, depending on its power, but that the same laser at a longer distance might not do damage even if it hits you square in the eye. Thats pretty...

    What power level is needed to clearly see the beam without fog at night?

    I've watched videos on youtube, and I'm talking LOTS of videos to try and get an idea of how powerful the lasers need to be before you can actually see the beam clearly, and not just see the dot when it hits something. But.........Many of the videos are shot with A. a crappy video camera or...

    Safety glasses: What % of laser light do they block? Any combo deals?

    I just ordered my 2nd, 3rd, 4th and 5th lasers in the last 3 days. The nly laser I own and have in my possession right now is an advertised 1mW keychain red laser. That being the case, I have not yet bought safety glasses/goggles. Now I'd assumed that laser safety goggles were going to be a bit...

    Whats the most powerful laser you can potentially design and build at home?

    I'm still learning a lot of stuff about this hobby, and at this point I could probably easily build my own laser at home if I had all the right components, but I wouldnt know where to start without diagrams and instructions. I'm sure there are many people here than can practically build lasers...

    How much does product quality fluctuate at the cheap-mid priced companies?

    Before I joined, I read a few threads and posts here about various subjects, and one I read was a basic thread written in 2009, I believe, listing the good, bad and ugly laser producers/sellers. Among the lower priced laser producers/sellers, there was mention that the quality of the lasers at...

    Concert laser shows: How powerful are these lasers now and then?

    Hi... I just joined up today, but I've visited this forum many times in the last year or so. But I am very new to lasers, so I thought I'd do some reading and learn at least a little before joining up. I also read the rules and suggestions for noobs. Having read the suggestions of what types...
