Fifth force? I will watch that video next, came to post this. Could be of interest to members just to see how bright a low power laser pointer is at a distance.

You can estimate the power output by the type of diode and known average power output at the current level the diode is pulling, but to do that, you would need to measure the current output at the driver output, not input to the driver. If you are talking about a DPSS laser, well, that isn't...

Yea, me either, they were small laser pointers, trying to remember the name.

Try Dragon Lasers: https://www.dragonlasers.com/ph-series-laser-modules.html They show a 80 mw output module for that wavelength too, but I am not finding the price. There are a couple of laser vendors selling them too, but both of the ones I found today I would not buy from due to over the...

I know where you can still get one :p I will reach out to you with info

Also, running the diode at a lower temperature (due to reduced current) will increase the life of the device. As a general rule, every 10 degrees C. of temperature increase reduces the amount of run time before failure by half. Many laser diodes are rated to run from 10,000 to 20,000 hours at...

The problem with running diodes in parallel using a single driver is, even if the same type of diode, one can hog more current than the other. If in series, they can each only draw what the driver allows, in total. Reason one diode in parallel can draw more and the other far less is because even...

Nice work! I wonder how they get 492 nm? Binned diodes?

I have almost pulled the trigger to buy one of those a couple of times now, just wish they made them for a longer wavelength. In the last few months I saw a post and photos a member here put up for one, quite an interesting device. Outputs were more parallel than I expected. I wonder if...

My same idea too, but I don't have nice springs like that, where to find them?

I have shims but no contact boards, except a few I purchased which are already populated with parts made for flashlight LED's I could pull the components off of, but would rather use a clean PCB.

I misunderstood the last post that the size was 2mm x 20 mm, when he meant two each of those sizes, just realized that after emailing Zack asking for a quote for five of the "2 x 20 mm" battery contact boards, he's going to be confused with that, so thought I'd better mention my error here. I...

561 is called yellow by some, it is more yellow than for example, 532 nm, but it's really lime. It is an unusual wavelength, that's why I like it, but not because I consider it a yellow color, or even close to it in my eye. If you want 575, those modules were the cheapest way to get it, too bad...

For myself, I would rather take all of their parts out and use them for my own RGB laser design which uses a rotator with a PBS cube to turn the polarity of the beam and then overlap in the same orientation than try to tweak theirs into something else. I don't see a way to add a PBS cube and...

I am not familiar with anything above 4 watts with proper design and orientation of laser diode output geometries. I am sure there are members here who do know of some 10 watt units with everything engineered just right, but I bet thousands of dollars. optlasers.com in Poland sells a 4 watt RGB...

At least with lasers, the parts are small, don't need lots of room but not cheap! I should say will likely end up that way, if you progress in the hobby and keep buying higher and higher level stuff. Doesn't necessarily have to be expensive.

Once hardened, that glue is brittle, torque on it hard enough and it will snap. If you are going to be adjusting things, or don't mid re-adjusting if it shakes loose later, no need to re-glue it. That appears to be the 10 watt RGB techhood was selling, I have one myself and had to realign it...

I wouldn't trust a regular cube with high power like that. only an OC PBS, or optically contacted and yes, $$$.

I guess once created it stays? Anymore who cares, we have high power 450 nm now too which I would think could be grouped with 445, 450, 465 etc.
