And low power! I don't limit myself to 5mW, but I prefer most of my lasers to be in that ballpark. :)

Nice pics! I really need to fill my gap between 405 and 473. That 447 of yours looks really nice! We have similar tastes in lasers I see! :D

Re: Aquarius 473nm DPSS problem? Lol yeah, there's no plural for "Aquarius" as far as I know so I had to improvise. :p My pleasure, my friend. Hope you enjoy this bad boy! If you want to do a little bit of reading about my Aquarius, and to get an interesting look at what the hobby was...

Re: Aquarius 473nm DPSS problem? For all dpss pointers? No. For the really tricky DPSS processes in tiny hosts such as is found in 594 nm Rigels or 473nm Aquari'i, yes; "near TEM00" is about the best you can hope for. If you'll go back about eight or ten years when Aquari'i were a hot...

Re: Aquarius 473nm DPSS problem? It bloomed a LOT in that picture and no one else viewing these pics will be able to accurately tell exactly how large the dot is to get measurements to verify your divergence. However, the hot spot in pic 1 appears to be 3/8ths of an inch, and the hotspot in...

Re: Aquarius 473nm DPSS problem? An old time veteran here to help a posting veteran. :) From what we talked about in PMs and from what I'm reading here, I believe your laser to be operating as designed. I've had an Aquarius for nearly ten years. Mine was from the first batch of pulsed blue...

Are these by any chance still being offered? I've got a 594nm Rigel module that needs a new home! :D

Ordered one from DL. Please close.

That is actually very encouraging! Deep down I know that DPSS/SFG is the most temperature sensitive process out there, but at the same time, if it was weak because it's cold, I'd probably have freaked a bit lol I'll put it this way... I never intentionally got rid of it lol. I'm sure it's...

***UPDATE*** The laser has been sent off for a hearty round of diagnostics. It hasn't been operated in almost seven years, so I honestly don't know if it is even still capable of producing 594nm light or not. I don't want to sink money into a futile endeavor, so one of our experts (who shall...

Shit like this is precisely why I regret how cheap lasers have become. On one hand I'm happy that I can get them easier, on the other hand, so can the idiotic masses...

Aquariuses (Aquari'i? :undecided:) are great lasers! I've had mine for almost ten years now. This one is from the first batch of blue pulsed ones, after they stopped producing the crappy grey CW ones.

So, I just ordered my Spartan from DL. Do you guys think I should email them and talk up my DSLR camera, a power meter and a review on LPF to try to get a ringer, or is it not worth the effort?

Just a thought, but if you reach out to some of the bigger companies like CNI, they might throw you a bone because you're doing legitimate science. It's always worth a try to reach out, explain what you're doing and see what happens.

I was asking for a 5mW.

CNI will sell you a module, it just won't be in pointer form. Knowing full well that I'm an American and plan to use it in a portable host, they quoted me $350 earlier this week for a 593.5nm module.

I love this thread.

Found this video whilst nerding out on YouTube. It is advertised as a 585nm non dye alternative to, well, yellow dye lasers. As a gigantic fan of yellow lasers, I've never heard of a non-dye yellow laser that fell into the 'true yellow' gap of 580-585. Does anyone know anything about this bad...

Thanks for the heads up. I reached out to him as well, but he hasn't replied to me either. Can't begrudge the man for having a life, but I figured it was worth a shot. :)

Thanks for the feedback UK. I figured there was a good reason that we don't see these and there damn sure is! Lol
