PSA: Cool down your 589s and check for extra lines!

Hello folks!

In the past few months, myself and a few other users discovered some strange properties of DPSS lasers, particularly 589nm and 532nm units.

When cooled down, certain DPSS lasers display anomalous behavior, including multiline activity and main-line shifting.
This is believed to be caused by defective mirror coatings.

It is possible that there was a 'bad batch' of DL Spartan 589s created recently. I have one of them... and by 'bad batch', I mean 'awesome because they emit 583.8nm when cold.'
So if you purchased a DL Spartan 589 recently, please try cooling it down on an AC vent, in a freezer (BRIEFLY), or outside in the cold.
Then check using a diffraction grating for any extra colors or color changes!

You can do this same procedure with a 532, or any other DPSS wavelength!

You should be reported to the authorities for making terrorist threats.

Waste of time. This idiot is just looking for attention, and should be banned at once.

Oh yeah, total waste of time. But imagine, on the off chance, they get locked up? I'd get a good chuckle out of that.

Great! You might get a pleasant surprise with a sudden shift, tell us your results! :D

Re: PSA: Cool down your DPSS lasers and check for extra lines!

Well I guess its time for a little cool down for my Spartan :D Lemme find my grating and see what happens:)




Edit: Well I tried it until the spartan was cool to the touch and when it was shining through the grating I couldn't detect any change in color with my eyes. Some of the dots created a little 3dot pattern though. It looked like this:

- - -









Not sure if that means anything though.

Excellent excellent. Do you see any difference in color - even slight - throughout those 3 dots? Do 2 of them fade out or snap out at some point?

Yeah the center one stays there but the right one dims to almost unseeable and the left one dims as well but not to the degree of the right one. The left one is certainly less bright than the center though.

No idea what any of this means :crackup:

Fascinating!!! Can you post a picture? Does the left one ever fade out completely? Looks like you might have a 586/589/591 situation here. It's a multiline unit for sure. :drool:

The best camera I have is my iphone but I'll give it a shot :crackup:
