I accidentally let this thread die. I was going through a lot back then.
Those were some good options, and I could use them on lasers I'm not as pumped about, but these are very important wavelengths to me, so I don't want to settle on anything but kinda close to the vision. Though that...
I'm in the market for a diode that's been confirmed in the 493-503nm range. I know it's narrow, and I should be satisfied by ~488/505nm, but after seeing the 496 and 502 lines on my Ar+ so many years ago, it's always been a dream to get more than a couple hundred uW of that...
Glad to see the flex drives are still around. I see they're still offered on DTR's shop. I won't even need to build another dummy load since the max on the low end is 100ma, and that just so happens to be perfect for both the Sharp 488 and 505s.
Neat! Thanks y'all!
I'm more settled in my new home, and now that I'm (still) unpacking, I've found a collection of old hosts and diodes that I haven't done anything with. I have a handful of unmarked de-canned diodes, another handful of regularly canned diodes, a 1W 405nm, a 505nm or two, and a...
I see that nobody replied to this...yes, HeSe is in fact a thing.
As far as I'm tracking, they never made it into serious mass production, but they have an insanely wide output spectrum. You can briefly read about a homemade rig here:

The full request is in the title, I’m looking for a custom built sand-blasted matte turquoise pen, or similarly slender host. I really want my upcoming 505nm build to pop.
I’ve got a ton of diodes lying around that I haven’t had the opportunity to put into a build, figure it’s about time...
I do plan to temperature control everything for maximum efficiency once I have a decent setup. For now, it's just about getting my feet wet again. It's been a while since I was last doing this thing. I still have my TEC driver, so once I get ballsy enough to try a more hardened setup, I'll...
I am aware of the requirement to mount it at either +45 or -45deg off axis. This kinematic mount will allow me to rotate the crystal housing as needed to achieve optimal positioning. I simply need a housing for the crystal.
Are any of these heatsinks exactly ⌀1" and direct diode press for TO18 and threaded for focusing optics?
If not, could I commission one? I need cylindrical heatsinks to mount 808nm DPSS pump diodes in.
