The rod is ar coated for external mirrors. :) if worse comes to worse, I can always use my quarter shrinker caps.

hey, new board is lookin awesome!

I was using a coherent ps, The label has been partialy removed, so I cant tell you the model no. :yh:

thats just beautiful! :drool:

I did have several more in with other stuff. have tested them all now. there are 32. The aditional ones are a slightly different tube, have the same model #, they dont have the built in ballast resistor.

lol! You actually made me laugh out loud with that! there are about 32 good tubes :crackup:

It rains them from time to time, and I keep having to pick em up off the lawn, no just kidding. lol.I did a weeks worth computer work for them and some other laser stuff.

They may be all spoken for, I dont know yet, but if not, then I may sell them. :D

I decided to test all my hene tubes today, I thought I had at least 40 of them, but there were only 33 in the box. Out of the 33, 8 of them were bad.

ok, got it, thanks! ill start there. :yh:

yes, for a month, and I'm doing that right now also... Thanks for the info, I am not familiar with this kind of meter, so I have no idea what I am looking for, I see there are opamps in it, but to tell you the truth, I dont know what they are doing with them. I had hoped someone knew something...

All I know about it is that its from a "Derma-K" laser system, I dont know who the manufacturer is. I believe they are based in isreal somewhere. What I really need is the sevice manual for the laser.

I was just wondering if anyone might know what the pins are for on one of these power sensors, I looked inside it, and it appears that it needs a + and - power source, but I dont know what else it needs to be used. Anyone know anything about one of these? It came from a dermaK medical laser...

Hey, I ment no offense. Sorry if I upset you. Disma

I'm just curious as to why there is almost no information about masers on the web, it would be interesting to actually build one. For those of you that dont know, a maser is like a laser, but instead of light, it is a microwave amplification device. Microwave Amplification by Stimulated Emission...

close, but no, its 694.3nm. I am still looking for mirrors for it.

lol, I think he wants to keep it, but I will tell him you are interested. The other rod is 4.5 inches x .25 inches.

Assuming this rod is capable of 20J, and the pulse lasts 1 ms, it is a 20,000 watt pulse. Of course avg power will be quite small. 1 pulse per second would still be 20 watts.

It would be easier if it does. (since I have 1 linear fl already.) I could polish a piece of aluminum flashing for the reflector, it might be a little heavier duty than a can. I was planning on using a corner reflector for the hr, still don't have an oc though.

I didn't think I would have to have a helical lamp... I'm hoping 2 linear lamps will be enough. No, 800.00 was way out of my budget! I'd have been more likely to have had the alien ship crash yield the rod! A friend of mine and I went in on a pair of rods. I was going to get the smaller one...
