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 pic two appears to be 7/16ths of an inch. This would give you a divergence of 1.056 mRad, better than mine.

Ok haha. Indeed it did.

I was thinking about it, and since I had it measured the original spot was around 25ft which would explain the "larger" dot. Im pretty good with DPSS but it's expected for pointers to go in-n-out of TEM00 & TEM01, right?

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 ticket for people to buy, you'll see a lot of people wondering the same things you're wondering about. It's fairly normal for these, though the various flashlight-sized-host 473 portables out there doubtlessly won't have these issues. Keep in mind that the manufacturing process for these hasn't really changed in a decade; Aquarius pens are all effectively ten year old technology. The module in an Aquarius (or a Rigel for that matter) is in dire need of a bigass chunk of aluminum to heat sink it.

Haha, sweet. Aquari'i is the new word you made huh? :crackup:

Ok, all seems well then. Thank you Chicxulub

Lol yeah, there's no plural for "Aquarius" as far as I know so I had to improvise.

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 like during my heyday in the hobby back in 2008, check out this thread:

We have seen the dawning of the age of Aquarius!
