people who think 9/11 is a conspiracy are nuts. Most of them also believe we never went to the moon. All these kids watch "loose change" one time and are converted to conspiracy theorists :crackup:

There is nothing wrong with it. That is totally normal when the batteries are dying. :beer:

If anything ends up being messed up on it and you want to recover any of your losses, I will definitely buy it!!! I've been looking for a broken yellow DPSS forever with no luck. :D

If I were a bit closer I would snatch that right up... Are you coming to Seattle any time soon? :eg:

Let me clarify.... if you are giving it the correct amount of voltage and current, and the arc is in the capillary between the anode and cathode, it should lase :beer::beer:

I'd say you're looking at close to 100 grand (or more) for the laser setup alone. Like you said, a q-switched YAG laser operating on third harmonic or fourth harmonic (355nm or 266nm) will be your best bet. As far as maintenance and other facility costs, I couldn't tell ya.

Nothing wrong with that!!! I do the exact same thing. I have a habit of aiming way over my head, and dont listen to people when they try to say 'start at the beginning". Then I end up trying for the top and end up wasting a lot of money, just to start back at the bottom again :beer::beer: Trust...

I honestly think Jack should be contacting you to purchase those photos for use on his site.... very nice.

I think what Ben was trying to say, is that you should always learn to crawl before you walk. Buy a small bonded crystal set and shine some 808 into it, you'll get green very easily. The next step you should take is to buy a little piece of Nd:YVO4 (with built in HR mirror on coating of...

The regular MSRP from viasho is already almost 50% less than opto prices without any group buy at all :beer:

yeah its just frustrating that there were a few for 125 buy it now a couple weeks ago when I didn't have any cash to spend... now the exact same ones are like 300 :scowl:

Very cool!!!! Keep up the hard work! We can always use more drivers around here.

If it were easier to use a 1064nm diode and directly double it, I think we would see it a lot more often. The bottom line is that the beam quality from a diode is SO far from perfect that it is very very very very very very very very hard to directly double them. Start with 808 and do it the...

Why? :thinking:

Yeah I dont want to comment on the financial situation at all, But I will say that the current is exactly 2.02A when it left my hands, and I had it tuned up to ~245mW, again with no additional stress to the diode :D:D Hope you all get everything figured out :o

I'm looking for a little 10W power supply if any of you have one laying around... I think it needs about 10kV @ 15mA... Just a guess. I know the operating current is 15mA, as the tube was labeled when I got it (said 14.3W @ 15mA) but it didn't have the tube volts :undecided:

Wow... I dont know how you can do this for $10 but if you can make it work and make a little bit of cash, more power to ya!! :bowdown: I was doing it for $30 and had about 10 builds a week at one point, but I realized that even at $30 I was losing money due to all the time involved. couple that...

yeah it can be done, but you'll have to wait for the good deals. If you're cutting cotton-like stuff (aka white material) you may not have a choice but to use gas. If you go with diode or even YAG to cut white you're going to need ridiculous amounts of power. With a focused CO2 you could...

Riddle me this... Why would a major manufacturer only give the good products to their distributors, and make their own products look worse when they sell them directly? If you buy a brand new car, will the car itself be any better or worse depending on which dealership you buy it from? Would...

Well... it doesn't really say "range finder" it says "laser range" but I do agree with you that the lasers in use are probably rangefinders for bombs etc. Pulsed yags pack some power... they can bunch holes in metal but not at any sort of distance. Probably a bullet hole.
