False Cheap 589's

Re: LOL Cheap 589's

Hehe, aye that is indeed quite possible, Yob! However, I'm keeping my fingers crossed that this pans out - ever the optimist! If it flops, I'm no worse for the wear; I have my Rigel!

Re: LOL Cheap 589's

There isn't $500 worth of parts in a Rigel HV, it's $500 of luck + binning (plus shipping, overhead, profit margins, etc).

I'd disagree with this, but only because if they just toss the dead ones, it'd add up to >$500 in parts by the time they get a working one out. I don't actually know how much more difficult it is to produce 589 (or 593.5, 473 etc) than it is to produce a 532.

Now, that may entirely be possible, but I am under the impression that currently the production efficiency for low power, pulse mode 589's is not that bad anymore. I've no hard data on it but the price would dictate it isn't nearly that bad or there is a surplus - and according to many reputable sources there is NO SURPLUS of working 589nm lasers. A few years ago, sure, but you can pick up a real low power 589 for <$300 easily now.

"Yellow" DPSS is all about Sum-Frequency Generation, which works by pumping a NdYAG or NdYVO4 with 808nm to lase at TWO lines simultaneously. I don't know if this involves specially doped NdYAG/Vanadate or just specially coated. It is definitely specially coated on the OC side to be OC at both the needed wavelengths though, that is for sure. The two lines are then summed in a nonlinear crystal (BiBO iirc) to produce yellow/gold/orange etc. The Nonlinear crystal of course also has to be specially coated on the OC side (at minimum) for the target wavelength. The real trick is getting two aligned, parallel, equal intensity, phase matched, commonly polarized, and high density beams out of one crystal and in to your nonlinar crystal in just the right manner.

Re: LOL Cheap 589's

I'm pretty sure it's coated or the lines are summed via optics. More likely optics due to it being possible to sum two different lines from two different types of lasing mediums.

Man, I'll be excited as hell if these are really only $10...

I'll be excited if these are <$100.

Re: LOL Cheap 589's

Pfft, that's terribly disappointing. :I

Probably need to do a super mega group buy or something to get anywhere near the listed price. P:

ROUND UP THE INTERNET GUYS

Re: LOL Cheap 589's

I am interested also.

Chinese?

Re: LOL Cheap 589's

Yep, that figures. Those quotes are even higher than what CNI told me.

Re: LOL Cheap 589's

G what do ya know, the yellow lasers don't cost $10. I got all giddy with excitement for nothing. I needed the $10 anyway for that $50 iPad I saw an ad for...apparently the company is overstocked on them and just trying to dump these low demand tablets. LOL.

Lulz.

Btw to edit the thread title double click on the background space around the title in the forum (not on the words, next to them).

 

[ZRaffleticket]

Whelp, this expands my search for another few weeks till I find another "cheap as hell" source. Anyway, until then, wish me luck

I don't know exactly what "cheap" will be, but whatever it is, I think we'll see it from the 561nm wavelength before either 589 or 593.

I know that sounds ridiculous since 561s are so rare right now while tons of forum members have 589/593. But while ridiculous sounding, it's logical.

561 DPSS is a familiar process. It's ND:YAG, and it's frequency doubling. 561 is very similar to the process for 532. Both 589 and 593 are much more complicated.

There are a ton of people making 532nm DPSS units out there (in China and elsewhere). Many of these manufactures would be capable of producing 561nm without too much pain. 589/593 would be a different story.

So is there incentive to making 561nm DPSS units? Not a ton, there isn't huge demand. But if a 532nm DPSS module maker realizes that they can sell a 1mW 561nm module for $100 bucks, it might not take a huge demand in order to make that a worthwhile brief diversion from making 100mW 532nm modules that sell for $25.

 

[Sigurthr]

Rhd's absolutely right. I'd jump on a $100 561nm module in a heartbeat. I doubt we'll see too much drop in the price of SFG technology in the next decade unless some commerical application arises (doubtful). SHG is tried and true and easily replicated with a very high success rate, no matter the frequency (when compared to THG and SFG). It's just too bad we don't have direct connections to some manufacturer other than CNI (who won't ship to US anymore!? and refuses to cooperate with new wavelengths), all it would take is a day with us and we could talk them in to all kinds of awesome stuff.

What did I tell you guys.. You won't find it cheap.
