Default HeNe tube helps

Hey all,

I was just given two HeNe lasers. *They are off brand and have rated max power of 30mW and 20mW. *Using a molectron PM, *they only put out about ~4mW each. *They have the original power supplies and the keys/lights/etc needed.

My question is how much work is it (or is it even possible?) to bring them back up in power? *Is it worth it? *I found Sams Laser FAQ but just looking for a second opinion.

Thanks,
Kristopher

If they truly are the "original" power supplies, then you probably cannot get them much higher. IMNSHO it is much too expensive to re-gass these just to have a cool beam.

Peace,
