What? The colors aren't far apart at all... they really don't have much of a difference.

Yes, they aren't far apart at all.

Sure, there's a noticable difference but saying they're that far apart visually is wrong...

I DID NOT say that. Let me try saying this a different way. When one looks at a white-light spectrum, the "yellow" area is much narrower than the red or green portions; the color change from the "red" region to the green region takes place over a relatively small band.

Aah! alright, but still 589nm still sin't close to lemon yellow
 
Maybe my eyes are a bit messed up, I though more close to 580nm would get into that region. Then again, I usually view 532nm or 473nm before the 589nm that would push it toward orange more...
 
Those lasers look SOOOO cool! I am on an extremely limited budget. Is it possible to get yellow laser for under $50? :yh:
 
A 589nm or 594nm, very, VERY unlikely. You'll need to find one at a garage sale to get that price. (don't count on it!)
You can however combine a red beam and a green beam to make it look yellow. If you find a cheap source of optics, you might be able to pull it off.

Thanks for the comparison shots. I was thinking about getting a yellow laser after I get a better green & better red. This helps me to decide on what nm to get.
 
Hard to believe there's such a big diff. in visible color from such a small nm change. Very impresive. Parital to the 589.
 
Just love the 589, Reds all seem the same to me unless they are super dark or super light
 
Yeah, Digging into the archives! haha I'm just buying my first real laser and I was just looking around at all the forums to learn a bunch of stuff :yh:
 
Amazing how much different they are visually for such a small difference in wavelength. I have owned a 593.5nm, but still have yet to get my hands on a 589.
 
For only 5nm between the common yellow wavelengths there's a pretty decent difference.

589 is definitely a golden color and 594 is more of an amber color. The colors are pretty close in person to that pic. 594 looks more yellow by itself but when next to 589 its amber color shows up nicely. FWIW the 594 is a 3mw HeNe and the 589 is a ~110mw CNI.
 
Most of the time the differences are because 593.5s are dimmer and less stable. There are very few comparison pics of here on 589 and 593.5 at a like for like power and when there are there's much less difference. I'm in the company of several SOX lamps which emit two almost identical lines at around 589nm and I can say it's virtually the same colour as the Rigel pointer in my sig.
 
I would agree that's damned near identical. I've never personally seen a 593.5 DPSS laser but it can't be much of a color difference than a 594.1 HeNe.
