Oh that's a pretty darn good price for a driver. The only thing I would fear with using LED drivers are the current fluctuations, but I searched around and many people did it, I guess I will try my luck.

Oh yes it very polluted.

Wow. I have never seen that before lol. Actually it doesn't even look bad I kinda like it. Quite unusual.

Gorgeous. Maybe I will get a few beam pics next to the Mississippi river this weekend. It glows 532nm by default.

BTW if you do decide to get it the switch you were talking about, and they want to charge you $50 to ship it from the US to Hungary, let me know and maybe I can help you out by buying it and shipping it to you in a small envelope which should cost much less. That is if the shipping domestically...

Couldn't agree more, Bill. While I am no optics expert, I don't see how a diode with a gbal collimating lens would output two beams. So I am really optimistic about this find!

Hi Robert, I honestly do not know much about choosing parts. This host was way too advanced for me. Hopefully someone here will be able to help out in choosing parts. Keep me updated and if there is something else I can help with let me know, but hopefully sinner or someone else here will get...

Welcome swan! I am sure you will have your fill of fun applied physics here.

The 85 one says continuous 2.1W. We probably can push that to 3W. Heck even at 2.1 I would bite

Nice find Bill! I can't wait to get one. Edit: Here's the none Gball version! https://www.laserlands.net/mitusubishi-9-0mm-to5-638nm-2-5w-orange-red-laser-diode-ld-ml562g85-01.html

PLEASE read about the safety considerations when dealing with your lasers, and NEVER allow your kids to use them unsupervised. In fact, I would usually advice against allowing access to them period, as these are not toys and can cause permanent blindness in milliseconds. Most of the lasers...

Do you live in heaven? Where ever you took that picture, I am moving there to retire. I wouldn't spend a minute indoors.

This is super informative. I am working with someone to perhaps make a 6x correction cylinder, and will probably just go with the Sanwu beam expander. Thank you very much!

Hi all, So after a bit research and asking around, I found that some believe that the Jetlaser's beam expander isn't really suitable for a high divergence diode such as the 44 or the 7475, as the beam might be clipped. In other words, choosing the Sanwu BE for such a laser is probably the wiser...

Hi all, You have probably already seen a review or two on these but I thought a few ore beam pics wouldn't hurt. To start off I would like to thank Gray for the phenomenal customer service and communication. Jetlasers truly changed my view on Chinese laser websites as they have proven...

Welcome to the forum! Do a lot of reading and don't be afraid to ask for help :)

I have my glasses on anytime I am running my lasers, unless I am pointing at the sky/trees far away.

Hi all, I wasn't sure which one to get, I was gonna go with button top just to be safe but I prefer less tension on the spring. What do you all use? :Cheers:

Man I can't tell what you can or cannot do but if you buy one please be very careful with it and protect your eyesight with suitable safety goggles. An invisible overspecs laser may reflect on shiny surface and hit you in the eye and damage your vision and you probably won't realize it till its...

That's one huge heatsink, I guess the size is Rich's signature at this point :san: The 520 beam looks incredible, I will have one myself soon hopefully!
