I just bought a couple medical systems and need some info/guidance/ect.

[Vidal Wolf]

hey guys. I lucked out and got two Coherent medical laser systems over the holiday.They are not in my posession *yet*
one is a Coherent Novus 2000 and the second is a coherent Novus Omni.
Would anyone share with me what the basic specs for these systems are? there is next to nothing info wise on the ol Al Gore intarweb. plenty of *for sale* systems and repair services, but no info on what the systems are/ what kind of lasers are contained within. Im confused about the 2000 system in particular,as the info ive seen is totally conflicting.. one company says tht the system is a co2 system,and another reseller says that the system is argon and anothe4r says its a yag/argon combo. it would be a wet dream to have it be all three,but I seriously doubt it.. I just hope theres a freq doubled green and a two watt argon in one and an argon in tthe other.
Let me know what you all know.
thank you in advance!
Nate.

OK, you have a bit of a issue here, as Coherent/Lumenis Technologies reused the names.

Also there are varients. One is medical power on demand, meaning the tube cant run cw. Actually it could, but the magnet is NOT cooled and melts. The other is more traditional and can run cw.

Varient One

The traditional novus gas runs off three phase with a Innova ceramic tube and comes in a argon or a krypton dermatology opthalmic varient. The tube can run cw at low powers. The tube is sealed mirror on one end or both ends, but..... The krypton sealed mirror tube has a prism or two different high reflectors sealed in the tube , and can select to run on yellow, green , or red. In krypton, 568 yellow and 647 red and 530 nanometer green can compete with each other for gain. So a stepper motor pair moves the rear plate
in x and y and peaks the internal prism for the color selected, this is all computer controlled,but I have seen a tech move the tuning stage manually. Yes, you can move it manually, but God help you if you ever loose the horizontal axis and walk the prism off resonance. Kr pressure is set low to favor long pulses, not cw. It will run cw to say a hundred mW or so for aiming.

Varient two. Power on demand. The tube will run off 220. But if the doctor only has 110, a complex switching power supply charges a humungous whale of a bank of computer grade 450V caps and runs the tube in short pulses. It looks like a shortened I60 tube clamped in fins with a uncooled electromagnet magnet. If you were to make a traditional magnet and cooling assembly, it would run CW.... But right now, you get what the computer decides to give you in terms of total energy.. CW aint happening without a lot of machine shop time as the tube is a bit to short to fit existing WET magnets. if you want to wind 2500 feet of #22 on a brass core, you've got a project on your hands :-)

OK, the good news. If the tubes are good, I have a medical friend who might trade you small (1-2 watt)brand new lexel heads for these tubes and end your pain.

And it gets worse, there can be, in a external box, usually built into the opthalmoscope table, a 2-4 hertz, 4 nanosecond flashlamp pumped 1064 nm yag head with a electroptic qswitch in it. My medical friend would want that yag head if its any good.

You take me pictures, I get you information.... dont expect schematics.... but maybe enough help to test these.

This stuff is all computer controlled, hobbyist style over rides don't exist.

If you get one of the tunable KR heads, and my buddy doesn't want it, I will take it off your hands.

aND worse yet is a varient with 4 selectable flashlamp pumped heads, yag, doubled alexandrite, ruby, in a box with a fast spinning prism mirror, the prism selects each head in turn and the computer fires the tube right when the optical path lines up with the fiber. Oh, and the doctor selects which heads he gets when he orders, you have no idea if you get 4 yags, 2 ir and 2 green, one ir and 3 alexandrite etc.

nough said.

WOW steve , you sure seem to know your stuff !

[Vidal Wolf]

Thank you Steve! Im a lightshow enthusiast,but Im also an experimenter as well. I might be perfectly happy working with the systems and kludging some sort of frankenstein experimental system.
Who knows, I might find a friggin shark and add lasers to it.
Of course I may just end up screwing up everything and ending up with a couple of giant doorstops.
But thats totally ok by me. I fix things for a living,and I love lasers,and I figure if I dont kill myself,and dont burn the house in half,then Im probably going to be learning a hell of alot about how these things are made,and how they work. Ive never had a Krypton before and Im looking forwards to seeing what these things are about.
theres also the real possibility that I will just take a look,get real nervous,and send yah all the pics I can and say *lets make a deal*

I need to open these up and see what I have. Ive seen them from the outside window of a sterile environment and behind a locked door,so I was not able to get in close.... I take delivery on Saturday.

[smogthemog]

Did you take delivery?

Did they work?

Steve, Can the Novus produce blue at any wavelength?

[Vidal Wolf]

Heyas.
Yes I took delivery of both sysems about a month ago.
The Argon Novus system did indeed work,we managed to fire it up and get it to run. then we shut it down and dismantled the system. the argon tube is sitting in a crate and the electronics went to ebay.
The omni is in my storage locker waiting for a trade to take place. Theres a guy that wants it,and he has a laser I can use , so its a great trade waiting to happen.

[smogthemog]

Did the Omni work and to what degree?

With it being an Argon, can it produce Blue?

Thanks for the reply BTW

[Vidal Wolf]

the Omni is a Krypton system.
according to Mixedgas, its a two *color* system. Either red or yellow. I have not powered up that system yet.

[Laser Zone]

We have an omni in our department at the clinic and the red is sweeeetttt, yellow is tasty too. Our unit runs on single phase.

[Vidal Wolf]

Hey laser zone.. Just outta curiosity, how many holes and slices do you have in you tongue from licking the laserbeams?
& what flavor is the red and yellow?
*laughing*

Anybody have any pics of a system in action?
