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...

DJZ, thank you for posting pics. I used the images to help me get an idea of what my reliant 1000M was supposed to look like. I bought one recently, not working and after much cleaning,and re soldering, I powered it up and it runs.

hey, I have a few new vids of my lasers on Yooutube. I also managed to buy a reliant 1000M for a couple hundred that needed repair. I repaired it and it works like new, very high power, maybe close to a watt. I havnt measured the output power yet tho. I like these two, side by side. =)

Sergi- Thanks for the awesome tip on the car wax. I tried it last week. I have a pound and a half of Gallium. Works like a charm! Fun stuff to mess with,but a pain to store since it wants to stick to everything.

Yeah, switchers, when they let go, its like somebody set off an M-100 firecracker inside a pinata *inside* a box. I had a reliant argon multiline that ate itself violently about ten years ago. The big caps went apart and fairly evenly distributed all the foil, Mylar and electrolyte in an even...

Thanks for the cool messages everyone. I ran it for a couple hours tonight to keep it happy. Heres a video from the first day I had it. http://www.youtube.com/watch?v=yikESsfEY-I enjoy! =)
