Lasering something

Howdy. So in my experience with He-Nes over the decades Ive found that as the tube ages and the gas gets buried by slow sputtering. The tube needs higher voltage / current to run. On the side of the power supply brick if you have the potted brick type, there sometimes is a small potentiometer...

Hey! Nice beams!

I had one of the 643 KrAr lasers for a few years and I would put ahigh reflector from a whitelight in front of the OC and get a ton of blue lines. I currently have a Laser physics 300 WC that does a nice R G B that's built into a projector. The colors you can get with a PCAOM and running...

did you ever get your 300WC fixed?

Hey. I had a 300 WC for a couple years. It had some pressure problems. I measured the wavelengths affected with an Ocean optics spectrometer. I loosely documented how adjusting the current level changed the lines that were lasing. Hope it has some value for yah...

Hello. I am finally heading out of the lasershow biz and will be selling all my gear. The first item is an ILT 5500 doing 600 milliwatts. 7 lines. I can only ship to continental US addresses only. Shipping costs are the buyers responsability. Thanks. -Nate.

Nice, very nice He-Cd. Ive got two older Liconix taht are pretty much, dead. =/ They both ionize but dont lase, the He pressures gone waay to high.

One night at the Plane-arium... I brought my Purelight star up to the Planetarium one night to give it some burn time since it had not been run in a year. Took her top off & ran it full out at 40 + amps for a few hours. Got the excess gas buried and the pressure and voltage back in the sweet...

*Yay* for huge giant gas power hogs! =)

Hey, UltimateKaiser, I just ran my Melles-Griot 643 this past week. Its gone a little blue from the lack of running for a year, but it came back into balance after about an hours burn. The arc struck down the return bore initially and I immediatly shut it off then on the second try it struck...

Here is a pic of the head..... =)

The father of the laser passed away earlier today in Berkeley, California. He was 99. Light a laser for a few minutes in memory him.

I bought a fairly average Coherent Innova 70 argon system thats been repumped into a mixed gas Ar/Kr. Supposedly it does 2.5 watts and works. I will have to wait to find out tho. Still, another whitelight ion laser. =) . Cant beat that with a bat.

There is no *cathode* to "sag"in a 107 / 127. the cathode is an aluminum cylinder. I own four and replaced the tube on one. Alignment is a bear if you lose lasing. the central tube supports are real fun to align as well. there is a youtube video from cambridge lasers on how to align a 107 tube...
