589 is lovely, but I now want a 583nm

I would love to be able to afford buying a batch to try my luck getting one. Chances are I will get the most spectral narrow bunch at 589 going.
Not that it would be too much of a problem mind you.

It seems my PGL-III-C is not as steadfast a 589 as I thought! I seem to have caught it today putting out two flashes (~2 seconds each) of 583 or another lower yellow after a cold start. Still, it maintained 589's main-line status the whole time.

Default Re: 583.8nm and 589nm, the golden brothers

We should have a look into the reasoning behind why they emit lower lines in more detail. It may allow 584 nm DPSS's to become more common maybe? I know that SFG of 1047 and 1321nm have achieved 584nm using Nd:YLF. But apart from 1321nm, 1047nm is quite far off 1052nm the nearest but weak Nd:YAG line. For 583.8nm you would need a 1047nm and 1319.5nm. Something very peculiar is going on in those 589's. It is almost like you have both a YAG and YLF crystal in there, but you obviously don't. The only thing I can gather is that there are more transition lines for Nd:YAG than previously thought, ones that require 'fluke' accurate alignments and particular conditions maybe?

Yes unfortunately owning a 589 is so much better than combining red and green together. Try and save up for one, they are worth it IMO.

Nd:YAG actually has way more transition lines than most people think.

1055nm, 1061.5nm, 1064.1nm, 1068.2nm, and 1073.8nm just to name a few centered around the dominant 1064(.1)nm line. Most are too weak to be very useful, but as UK already suggested, temperature fluctuations and mirror irregularities may cause them to show up from time to time.

Yes there's a whole variety of things that Nd3+ will lase, just like any other medium... but remember a line has to have a use to go commercial. Many of the lines in this area are not used much, and have very niche markets. There are plenty of lasers out there that just don't have a market. They certainly exist though. Demand drives the technology- this is how the metal vapor lasers disappeared, along with a variety of other gas and SS lasers. This is also treapassing on the area where the dye laser has always been prevalent- which is far more powerful, and tunable as well. Many of the applications in this area require a lot of power, & solid-state is only just starting to be able to catch up to the dye laser.

Wow, what a beautiful wavelength!

Aren't you affraid of damaging or lowering lifetime of your Spartan by low temperatures and longer use than recommended by DL?

Just curious as I'm awaiting one coming soon - so I'm looking forward what modes it will produce.

BTW: I did not find an internal scheme or photos of 589 nm Spartan's module to see how it actually work (I have just seen some other 589 nm laser schemes).

Cyparagon did a review on his 589 Spartan and showed it could be run for 30mins without any major problems occurring and would still work fine. However, for safety and a longer life the duty cycle of 1min is probably the best way to go. That's how I ran mine

Ultimatekaiser has a great teardown of a 589nm CNI PGL module from a few years ago here:
Disassembly of a 589nm laser PGL-III-A (PIC HEAVY)

IIRC, the spartan uses modules from CNI, so it should be very similar or possibly even identical.

Thanks a lot Hap, H2Oxide and CurtisOliver.

I have seen that review earlier, anyway I went through it again. Whatever I do not plan to use it much above a duty cycle.

So, there is not any complicated optics for merging 1064 nm and 1319 nm. I couldn't imagine how they could fit it in the module. I supposed it will be similar setup as 532 nm. Great to know, for portable laser I was affraid of misalignment due to possible mechanical vibrations during transport.

Any concern remaining now is using the laser in low temperature and its impact on 1064 nm/1319 nm crystal(s) and its coatings - but I think if it is treated as 532 nm, this shouldn't be a problem. Thanks again, guys!
