589nm misbehaving - wrong wavelength!!

hmm no wonder why CNI have a big discount around 4 months ago on these yellow pointers and for a limited time they offers those obscure WL pointers...

*604nm dpss is available in hand held but the price tag is high...

I never heard about this... What WLs? GLP or PGL? What's the cost?

it's happens to the PGL.

those specialty WL cost absurdly high.

it happens to the dpss yellows.

* it a costly mistake that gone horribly right for CNI.
If anybody notice a bunch new WL that was added to their product list, they are trying/successfully to reproduce those phenomenon.

there are quotes to describe these situation but i'm too lazy to do a google search.

Anything is possible as long as you give CNI enough $.

604nm has nothing to do with yellow..

604nm is made via 445nm pumping PrAYAC. Pr resonates at the low 600nm spectrum. The wavelength is determined by the lattice. Much like Nd:YAG lases 1064nm but Nd:YLF resonates at 1047nm and 1053nm; PrAYAC lases at 604nm but Pr:YLF lases at 607nm.

Yes. Although that's not what I think theyre talking over. And Pr's main line is not orange FYI. The main lines are actually 640 and 479. The oranges are far weaker. They may well be used in projectors possibly for their RGB qualities.

After some tests with a diffraction grating, it is clear beyond any doubt that this laser's main wavelength is 589nm, NOT 593.5nm. It will take some time to test the other wavelengths.
Edit: I verified my results by checking a 532; the result ended up being 532.7. So it is correct to the nearest nanometer. I also used it to measure my LaserBTB HL, which ended up being 457nm, and my eBay Thor "520", which ended up being 513. Interesting wavelengths, but not too unusual. :beer:
