Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Does anyone need an argon laser retinal photocoagulator? It should have at least a couple of Watts of multiline output. ZEISS SLIT LAMP ZLSA.02 ARGON II LASER HUMPHREY INSTRUMENTS !!

At the moment it is disassembled and put into storage. I'm trying to get running a big argon laser but have trouble with the power supply. After that I hope I will return to this project, possibly I'll re-assemble it customly on a thick aluminium plate instead of modifying those LTI-501 lasers.

Thanks for your replies. AFAIK, Brewster windows of He-Ne tubes are made of fused quartz. And yes, the Brewster angle is wavelength-sensitive because the refractiotion coefficient is different on different wavelengthes. But as for quartz -- it has n=1.53 at lambda=1.2 um and n=1.54 at lambda...

BTW, I've found a shard from a big He-Ne tube with a big Brewster window. Will it work as a polarizer if I put it into the resonator of the YAG laser? How can I make sure then that the laser beam is polarized?

I cannot decide what to do first. I have 2 argons which I need to get running, the GOS1001 unit and the LOS4M dye laser. Argons look like to be the easiest ones in this list, but still I can't decide. Probably, at first I need to take away the CVL power unit and other stuff from my table to have...

I don't have a proper power meter yet. I have found one, but than it turned that it measures energy in Joules, not power in Watts, so it is for single-pulsed lasers.

The CVL project is finished! The laser head is complete now!

Very impressive. Very beautiful wavelength. But still it is more profitable to buy an old gas (CVL or CuBr) laser or a DPSS for those thousands of dollars. At least you'll have 1 Watt of 577\578 nm. Sorry for criticising. By the way, my CVL is portable too -- the laser head has a handle on it...

25) My new find -- a bunch of Nd:Glass rods. The biggest one, 45*620 mm, is a spare for GOS1001 laser blaster, the second is 30*620 from an unknown laser and it has a fatal damage -- a big shard of it is chipped. The third is 20*270 mm and all other small ones are from laser welders.

The NOS Nd:YAG rod for pulsed laser is sold.

I would be also interested in exchanging the items from this thread on other lasers or laser related equipment, instead of money. I am interested in old and powerful gas lasers. Glass argon/krypton ones and Cu\CuBr lasers are in the highest priority.

Bump!

Unfortunately, I will possibly disappoint everyone in this thread who hopes to get some laser light from the uranium glass. As far as I know from my old dusty books, _there_were_ solid state lasers _existing_ that utilized Uranium U3+ ions as an active medium. These ions were put into CaF2 or...

Today I've squeezed everything out from my CVL tube. With the improved power unit I could push in 2.2-2.3 kW of power and got much more yellow light than in previous experiments. The beam is much more "lemon" in colour, not pure green. I think I have 5 real watts of light here, it burnt wood...

It is already working and I got some nice lasing yesterday. But I've encountered a problem that with the raise of the voltage I got sparks and arcs in the places where they must not appear, inside the Blumlein generator. Now I'm improving the insulation and adding a snubber circuit for the main...
