    Will this Damage my Sanwu Pocket Laser?

    Thanks to everyone for the suggestions and great information. Cyparagon, that is exactly what I needed to know, so I really appreciate you taking the time to test your laser! I ended up ordering my dad the 50mw 505nm Sanwu Pocket laser. After reading more about the 405nm wavelength, and...

    Will this Damage my Sanwu Pocket Laser?

    Thanks to everyone who replied! Sanwu replied to my email and offered to reduce the output of the laser as a custom order, which I had heard they might do -- pretty cool of them. They also said it should not cause any harm to the diode to run under-voltage with a AAA. To clarify, my fear with...

    Will this Damage my Sanwu Pocket Laser?

    Thank you for the reply, Encap. I did send an email to Sanwu customer service asking the same question, but I respect the knowledge on this forum and figured I'd ask here as well to see if anyone had any opinions. I do know that 405nm is much less visible, and I have several 405nm Ebay lasers...

    Will this Damage my Sanwu Pocket Laser?

    Hey Everyone -- I was wondering if anyone who knows more about the diodes and drivers used in the Sanwu Pocket lasers (specifically the 200mw 405nm model) could tell me whether or not I would damage the diode by running the laser on a 1.5V AAA instead of the prescribed 3.7V 10440 battery. The...

    NEW TOOL: Calculate Relative Brightness (of Wavelengths in nm)

    Sorry to resurrect old threads, but the tool has stopped working -- please let me know if there is anything I can do to help get it back up! It was very useful to me, and I miss having it already. Is it the ASP hosting again? Or is it just me that is having this issue? If it is ASP or hosting...

    750mw+ HL445 LaserBtb came!

    Is there any way to adjust the focus ring on these lasers? Basically I want to make the infinite focus focus to a farther infinity (if that makes any sense haha). It goes wayyyy pas what I need it to do in the other direction, but at infinite focus the divergence is pretty bad by around 30...

    750mw+ HL445 LaserBtb came!

    Hey everyone finally after a month or more I have received my powerful laser. It is a 750mw HL445nm laser from LaserBtb.com and it is fantastic! I am using two 16340 batteries from AW ICR. I received these batteries around 2 weeks or more ago and haven't charged them because the charger came...

    Libra, Anser and Aquarius through diffraction grating.

    Yeah shower steam is perfect! That would look awesome with the diffraction grating. Multiple beams from quality lasers. Can't beat it haha

    3.0mw vs 5.0mw

    Haha yeah alright I think I'm going with UPS first class. I am still unclear on what an ePacket is though lol oh well. I don't think anyone actually knows!

    3.0mw vs 5.0mw

    Wow you guys know wayyyy too much about this stuff lol I guess I'd better start learning! There's a lot to catch up on.... And does anyone have experience shipping from Fasttech? I don't know what to choose! I've never seen so many options....and all of these are free! Should I choose USPS...

    3.0mw vs 5.0mw

    Yes I know they are haha and if I see a group buy when the time is right, that's definitely what I'll do. Apparently they're very hard to make, but the color is worth it!

    3.0mw vs 5.0mw

    Awesome thanks! Gonna be ordering one of those bad boys. And huh I guess I've just never noticed that myself before. That's good info too on the 473s, I never knew exactly why they were so much more expensive but that makes sense. As soon as I get money together again, I may be in the market...

    3.0mw vs 5.0mw

    I definitely have a lot of respect for LaserGlow, and CNI for that matter. I figured 473nm was that expensive haha I was hoping maybe you guys had found a reasonable one at a china website somewhere or something! Oh well one day I'll get one. Sounds like you got a great deal Blackwolf! Yeah no...

    3.0mw vs 5.0mw

    Yeah in the end I am going to buy a cheap laser like that 5mw on fasttech's site. If you endorse that one, then maybe I will get that. How was shipping and does it have a good beam/low divergence? Also how much did that 473nm you had set you back and where did you get it? That looks great haha

    3.0mw vs 5.0mw

    Yeah but if I went with $50 I'd buy from LaserGlow over WickedLasers. Just from what I've heard around the forum, and also because I've always admired LaserGlow (it's like admiring a nice car brand haha). Nice avatar by the way Blackwolf! Haha

    3.0mw vs 5.0mw

    This may be true but unfortunately because I didn't realize how much my 750mw laser would cost all-told (after tax, shipping, and batteries) I sorta overspent and I don't have any more money lol. Being a student, I'm sorta on a fixed budget. I wish I could get one! Getting a pure diode laser...

    3.0mw vs 5.0mw

    Thanks for the offer, and now that my order from LEDShoppe didn't go through and I would have to re-order anyway I may be interested. It depends though, I really don't want to spend a lot of money and I don't want to lowball you for what I'm sure is great work. I couldn't spend any more than...

    3.0mw vs 5.0mw

    You're right, I decided 5mw was not quite enough. But, I don't want to go all the way to 50mw either, because in all honesty I don't plan on being too too careful with this laser (I'm gonna treat it like a 5mw). So, 20mw seems like a happy medium, and I'm sure that beam will be enough with a...

    3.0mw vs 5.0mw

    Haha 1.5W in a pen that size! Very impressive. Congrats on the successful build! That's running on 2 16340 batteries or are they 18650s? And btw I just wanted to mention that laserbtb is a generous website, I emailed Kevin about whether or not the laser I ordered (the 750mw 445nm HL) comes with...

    3.0mw vs 5.0mw

    Thanks for the tip Tmack, but I think I am going to stick with a pointer rather than a focusable laser as this is something I am going to carry around. My brother might want a laser though so that seems like a good option for him to have a sort-of powerful green laser for cheap. The mini 20mw...
