So cool. What's your pump source? N2 laser? Damn, just read the post... you're using a TEA N2 laser, right?
-
@41ch It might be superradiant, which wouldn't require a cavity.
-
I also don't see a conventional mirror cavity; could you describe how this particular setup works?
-
How is the dye being pumped? Do you have any more photos or video? I would like to see some detailed shots.

Excellent and impressive laser. Now you can try using a dye that emits broadband and thus tune with a prism or diffraction grating.

Thanks!
Tuning is best done using a TERP (Transverse Electrode at Reduced Pressure) N2 laser. The one used here is a TEA (Transverse Electrode at Atmospheric pressure). TERPs produce longer pulses.
Search for Jon Singer on Google. He has done it all - from tuned dyes to white light laser dyes. His work is impressive beyond explanation.

Try antifreese diluted to about 10:1 denatured alcohol to antifreeze, it works even better :o)

Really!? Wow. Thanks for sharing.
10 parts alcohol to 1 part antifreeze then? Will 91% isopropyl alcohol work?

The output seems to change in colors: is a problem of the camera?
I would make some dye lasers but my TEA-nitrogen is too weak because I don't know to buy pure nitrogen
rachm06 3 years ago
Yes. The color appears to change somewhat because of the camera. But this is only a camera effect.
You can lase this witout nitrogen. Go to jarrodkinsey dot com.
This is my website. I show how to build a good laser that will lase some dyes without nitrogen. But the output will never be very good until you get some nitrogen. Go to my website. Build a TEA laser like the ones you see on my site. Once you use this laser to lase dye with air, then you might be motivated enough to buy nitrogen.
