I had today off so I went and tested each laser module and thankfully they all work! These are the companies first batch, they had a bit of problems with them fluctuating wavelength, and power, and just overall not being too their standards. They won't be making anymore for about 6 months+ until they figure out the problem. Once they do fix the problem they will be increasing the price of them much higher, at least that's what they told me. They don't have drivers for them so you will have to buy them. 1.9V 600mA is what's required for them to lase. I'm using the ACS5500BU that DTR is selling.

The price of these will be $110 shipped to the US. I bought them for $90 each and the extra $20 will cover shipping and packaging. Here is the list of the 563nm-571nm for sale. https://docs.google.com/spreadsheet...pq01hoNq93Qs8W8LAdyvikkuc/edit#gid=1463621074
I am also limiting to selling 1 each to member so more people can enjoy them and not just one person buying all of them.

#2 sold
#10 sold
#12 sold
#16 sold to Mattronium
#17 sold
#19 sold

I also have 1 561nm module and 1 560nm module for sale. These do have drivers. They require 3V to lase. I bought these for $125 each and am selling them for $145 each. https://docs.google.com/spreadsheet...pAW0JhNMXaZ3_DqdsXKZwoxCo/edit#gid=1835442585

#1 sold
#3 sold

This website is decently accurate to show off wavelengths. https://academo.org/demos/wavelength-to-colour-relationship/ I have this Tuesday off so I'll be shipping them out then. Thanks!

Received the module today, is red positive? I've seen red represent negative more than once in the past, so I no longer take chances. Red really means the polarity above ground, does not mean positive.

The 561 nm module is very cool.
The color is quite unique (maybe less so in the future) and the driver is PULSED!
I haven't attempted to measure output power yet but it seems in the 3-5 mW ballpark.
When I get around to putting the module into a project I'll be sure to report on beam quality and all that but so far it looks good!
I'm glad I jumped on this opportunity. The transaction was straightforward - no funny business expected and none was experienced.
Thanks, SuckPit.
Unfortunately, I can confirm that photos with any camera do not report the color properly. I'll have to try harder but for now, I'll attach a crap photo to show the dashed pattern that results from the pulsed beam.

So these have a driver already? Thought it was sans driver. What’s the voltage to apply if it has a driver.

Thanks Pierce! It's quite odd of a color and hard to capture with a camera. The small 561nm have drivers. They just need 3V to lase.

Do you know what diode is used in the 570 nm units? I'd like to research the pump diode used without tearing this one down.

The last batch was supposedly 976nm for 575. I have one with a dead pump. I was meaning to play with pumps. Now that these are here think I shall.

I'm not sure what pump diode they use sorry. If you want I can send a message to them and see. Also BUMP still have 6 modules left for sale!

Hey this is probably too off topic, and if so please just let me know and I'll delete this post and put it up somewhere else.. but does anyone remember those pictures of the crystals DTR posted about the time these lasers were coming out, which showed a crystal being pumped by a 445 pump diode and outputting yellow out of the crystal? Whatever happened with those I wonder?
