[QUOTE=RonZ;135786]Adam,
I've been quietly lurking on this site for several months now. Have been taken in by lasers since I was a kid (that would be about 4 decades ago) but never really able to pursue interest either professionally or as a hobby until fairly recently. Even so, I have much to learn and little to contribute hence the lurking. Anyway, your thread drew me out because, like you, I also got a bargain on a medical laser. I have a Surgica K7. It contains three tubes. One is simply a 5 mW randomly polarized HeNe aiming laser. The other two are either both Argon or one Argon and one Krypton (no red in the presumptive Krypton so not really sure). One is rated at 7 watts max output, the other is rated at 2 watts max output. I don't know what they are actually putting out since I can't measure but the 7 watt tube is outputting at least a couple of watts (probably more). Like yours, it's a completely self contained unit that runs on single phase 220 V. All three lasers work. The Surgica focuses the output into a fiber optic delivery device. I ended up removing the output coupler of mine (and defeating the safety interlock that comes with it) in order to get an uninterupped and unexpanded beam. When I get a chance I will try to take and post some photos. I have passed the beam through a diffraction grating and I get 7 colors. It's actually very pretty, and very dangerous. As Steve mentions, it's pseudo CW. You can run it CW for a short while (I wouldn't go over 20-30 seconds) before risking overheating (though it does have protective circuites that will shut it down if overheating). The front pannel controls allow you to set power, pulse duration and number of pulses when not shooting CW. It really is a lot of fun. Hope you get yours working.
OK, you have the argon, doing the 7 colors, and the krypton doing a yellow-green correct?
Usually 2 yellow and 2 green lines from the KR. Kr yellow green = 520-530-568-575 nm.
Is the 7 watt number the danger sticker power, or is that what the system is delivering? On the sticker, the power is usually 2-3 times what the system is rated to deliver.
