"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."

Absolutely correct. 2 yellow and 2 green lines.

"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."

The 7 watt number comes from the User Manual as the max power deliverable to the input of the fiberoptic cable. The front panel also allows variable output power setting in (I believe) 100 mW increments up to a max of 7 watts.

Ah, you have a E8 style tube , however with sealed mirrors...
In commercial service with brewster windows and the correct fill pressure for CW, that core is probably a ALC905

BTW, welcome to PL.

Please take a look and see if you have some loose 4 pin molex connectors around the back of your tubes, HGM usually brings them out as a way to measure tube current with a floating DMM.

Thanks Steve. I'll take a look.

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.

Best, Ron

Hey Ron!
Glad I broke you of your silence. Please post pics of your K7 up and running. We'd all love to see it.

Hi there 300EVIL,

It just so happens I just purchased an HGM K5 Spectrum today. The one I have is in much worse condition, but does in fact have two tubes - - one argon, one krypton...

How can you tell if it's gas intact? Have you been able to power your unit up? Mine gets stuck at "E10" error. I'm starting to research how to bypass the computer and make the power supply just fire it up, but it seems tricky. Happy to work with you, as I suspect based on the photos you and I have nearly the same laser. I don't come here often, but you can email me at 3ricj AT shmoo DOTTTY com

Cheers!

[QUOTE=300EVIL;135612]Picked up an HGM K3 Spectrum today for a couple bucks. It's a multi-line argon and is gas intact. Sadly there was no foot pedal or controller so I have some work to do to get it running. It's a pretty neat little self contained water cooled laser with a big pump and radiator for short bursts. I have no clue if it will work CW or what the output power would be if modded for CW but it's still cool.

e10 = no fiber

remember, its pulsed. Just a maybe 10-20 seconds per pulsed followed by a cooldown.

Evil,

Saw this old post now... Did you ever get this working? I have some fibers and can probably provide the pinout for the foot controller...

Please provide the pinout to the janitor also...

Wow necro-postage!

Adam, I didn't know you work on the side as a Gynecologist....

Your not a Gynecologist? But you'll take a look at it right?
