Who here is feeling gassy?

Those are nice, keep em coming. :kewlpics:

Very nice! But what laser is that with? It has to be gas

It is All 54mW of it

I do not approve of shopped laser pics! :tsk: :eg:

I really hope that's on the outside of the tube.

On topic:
I'm getting another HeNe in a few days. This one will be 15mW!

 

[diachi]

looks good! What power was it doing there?

 

[GooeyGus]

probably like 5W or so, I think I was at 25A-28A

Nice one!

I wanted to ask - do you notice the colour change as you ramp up the current? IIRC the green lines have more gain than the blue lines at higher currents, so does the colour shift?

 

[GooeyGus]

Yup! It's more blue at idle, and as you go up it shifts more to the green side. Pretty neat!

 

[Cyparagon]

Do you get the 528-something line at high current like I do?

 

[GooeyGus]

I don't think so, but I don't think i've ever diffracted the beam at full tilt. I think the highest I got was like 28A and it started melting the (very robust) holographic disc we were using to split the lines.

Damn that's cool! Always wondered about that after I heard about the green gain being higher when the current is higher!

While I don't have anywhere near a 5W argon, my lil Uniphase does 5 lines at idle, adding the 502nm line as the current ramps up to full.. This causes the beam to go from slightly bluish to a greenish turquoise.

haha , that's cool! I'll need to see if I can get the current to vary on my ALC60 when it arrives. That or I can just have fun with that and my PM21 and other new toys .

Only got a 2211-20SLE just now, with no fan. So I can't do much until I get a fan.

Cheers!
