574nm 36 mW Yellow Laser

I cant do much beyond speculate, as i dont have one in my hands. (I know, I was late to the party) I could do testing on the crystals and diode, but only if i had one to dig through and play with. The 565s are probably similar. 561 can be made several ways as well. Its hard to be conclusive without a physical sample. I have lab grade drivers and stuff so itd be interesting to play with a few if i can get my hands on one. It strikes me as they appear built in a similar manner to my old Aries module.

I could also compare them to my opsl units and other lasers in that area of the spectrum. Though catching that on cam would be hard.

In this thread I posted a schematic of the Nescel opsl 577 nm laser. Note the doubling crystal is not named.

The photos of the 565 nm laser appear the have similar features as the Nescel.

Ground floor?
Nobody is offering any of them as handhelds is just a matter of finding someone that will do the job if you supply the parts.

Precisely the point.

I have THE first 405 pen in the hobby, one of the first ever examples of the blue CNI 473s, I had (but broke) one of the first CNI 594s, I had a double-digit serial number Leadlight 532 and now I want one of if not the first one of these in a handheld. The stuff I value and hang on to is a bit different than what most members here care about.

Maybe order the 575nm module from China first and see what you think? Email Freeman at OPT and ask for price and delivery: email him at fb@optlaser.com

I plan to, thank you :)

I got it--you want a form factor that isn't made/manufactured/offered---a custom, hobbyist made laser in a "Spartan" host with one of those OPT modules in it if someone will do it for you. Several LPF members are capable of doing it if they are supplied the parts.

If you want that "Spartan" host and don't have one - email CNI and see if the will sell a bare "Spartan" host which they call a PGL-III-M host -- email: sales@cnilaser.com

I’m betting I could do it. Lol i’d actually probably turn one of these into a lab laser. And to be honest the main reason I didn’t buy one is because I don’t particularly need one, but I’m more than a little interested from the science side. I usually as a rule of thumb also don’t take apart working lasers, but in some cases it’s just too interesting to pass up sometimes.

I was the first person to tear apart a yellow 589, and to fix one, so it wouldn’t be my first time driving into something very complex and putting it back together. Although these do look to be pretty simple.

I should probably get in contact with someone here who has a lathe-I could probably make all kinds of crazy things if I could machine my own parts. I could probably turn one of these into an actual stabilized laser pretty easy with a pair of peltier coolers and quality mounts and a B&W driver. Or into a custom handheld.
 
Bad news on the CNI front, I tried that already, less than a month ago. If you're in the US, forget it. They won't sell me any of their empty hosts nor driver boards they use in portables

CNI is not a hobby shop so it probably doesn't make much sense for them. To start doing that would probably cost more in paperwork than it's worth would be my guess. Would be a waste of time/no money to be made in doing so.

For sure they will not sell complete hand helds which are illegal and is the reason the were put on the Import Alert 95-4 list in 2015 which they are trying to get off of. See: https://www.accessdata.fda.gov/cms_ia/importalert_254.html
As replacement/repair parts for verified CNI units some members have purchased parts--was a while ago so maybe they have stopped that also now.

Perhaps Dragon Lasers would be wiling to order and resell just a host or driver--who knows---might be a waste of time for them also?

Is anyone outside of the US able to get hold of them? If I could afford to and knew how to go about it, I would start placing orders for their hosts and then make business selling them to US and AUS customers. That way, everyone can use them on LPF.

If all else fails, you might have to change your desired host for a handheld one of these lasers. It will need to accommodate a 20 mm module.

I can order them, will they ship to all countries except US and AU?. Need to ask CNI. However I have low budget right now.

Pleasure to work with this host.

I’m presuming most countries will still be ok. It’s only those that have restricted handhelds.
I’m also on low budget otherwise i’d volunteer to buy and relay a couple.

I noticed you sold the handheld 575nm laser you built. What kind of duty cycle did it have outside the lab host? Seeing how hot the original driver got, it must have gotten warm to the touch within a limited time frame. :thanks:

Government restrictions wouldn't apply to an empty host/parts-- only to complete hand held lasers, however, maybe as a practical and business matter CNI won't ship hosts either---who knows?

Am sure if CNI wanted to be in the parts to DIY hobby people business they would have been doing that already --so maybe they just don't do that as a policy.

Nexgen should email CNI and ask if he can buy a couple hosts and cost for same + shipping which is always unreasonably high with them
