Laserscope "Orion" service manual or diagram for service plug?

[rszemeti]

Hi,

I have a Laserscope "Orion" 30+ watt "Z" fold laser, and *almost* have the thing running, but I need the one last alignement of the output detectors to get it going ...

Anyone know where to find the service manual *or* how to get it into service mode? I think it needs a plug with some jumpers in the service port in the back, but would prever a diagram before I go poking wires in ...

NOTE: no answers of "its easy to rip the control stuff out" please, and no answers of " have you looked on http://www.allen.dj/laserscope/ ?" .. thats the 800 series manual. (but the error codes on there are handy

I've seen at least 3 different service plug wiring schemes, as well as the service prom.

I'd need to much know more about you then 1 post allows before I can tell you anything about 'Scopes. House Rules, and the rules are there for a VERY good reason after some past incidents.

Unless you like expensive showers of sparks, I would avoid the "poking of the wires". You can end up poking VCC into a non standard serial port that may not like it very much.

So tell us about yourself, where your at, how old you are, and what you intend to do with this beast. If your shy about posting such data on the net, pop it into a PM please. See have been two incidents that have scared me, and thus ethically I have to ask...

Thanks for the warning, I am a qualified electronics engineer, with more years of messing with high power electronics than I care to remember.

I have previously owned and played with various lasers, most in the multi-kilowatt CO2 class (roots blower trumpfs upto ~2kw, various argon ions, even an 1600W Optomic coaxial laser, now theres a rare beast .. still got the head, but not the 20KW "Henry" RF power supply) .. what else, oh a Haas HL703D 800W YAG ... thats probably the biggest fibre delivered laser I have had to play with, Ferranti 300W CO2 was probably the oldest one ... between me and my mate I think we probably have over 20 various lasers lying around in various states of test bench fun. Hmm .. actually I take that back on the Haas HL, thats the biggest one I got running, theres a 6 cavity Lumonics laser welder in the back of the shed, but never got it to fire

I am fully aware fo the dangers etc, the Laserscope is probably the smallest laser I own right now I am also aware that being Q switched, the peak powers are up around 20kW, and all that entails.

Does that help?

As for "poking the wires" .. I always meter them for volts first and use a 1K resistor ... not wanting to blow up any TTL just yet!

Qualifications far more then acceptable, Sir. Welcome to PL.

A PM will be sent within 24 hours with the one combination that I have. I'll try to point you to the right place for a manual.

We worry about 'scopes, least some one who is naive, tries "audience scanning" effects with one. It has happened overseas with a similar industrial model.

Do watch, that design does like to bite the hand that feeds it, when the covers are off. Even the scattered light can easily hit class IV. Lots of hot, stray, beams in those.

PS, You could have stopped at "Roots Blower". :-)

No worries,

We have one running just fine already, been playing with it for a while. 10W into a 100u spot is very kewl

That one was a non-worker, but it was just the beam alignment mirror after the PR, ther are two aiming screws accesible fromt he front, someone had backed them off and it was hitting the attenuator block ... a quick tweak soon had it up and runing, and we have fibres for it, oh yes We put a collimator from a big Trumpf welder on it for a while, 50mm window and that worked very nicely.

This second one we have stripped the fibre launcher, bodged the fibre connector, made up a calibration adaptor to fold the beam back into the cal port .. and it calibrates at around 80% transmission and is good to go.

There is a mis-match between the safety detector and the surgical detector, from what I can discover, it needs the two to be fairly close before it will fire ... at the moment, soon as you hit the footswitch, it flashes a brief pulse, spots the mis-match and throws a fault A05. I tried baalncing the gain of the two sensors on the test points, but I guess I need to get it into service mode and see what the microprocessor is seeign out of the A->D convertors to get it going ...

Noted on the audience scanning .. was that the "las vegas" incident? I can imagine the damage .. 20kw peak power is NOT fun for the eyes ...

PS, note this is the "Orion", not the 700/800 series, which everyone on the planet has the manual for, and I have the service plug info for that one already.

I was thinking the Russian incident

not heard of that one ... how many got sliced?

Pretty obvious really ... you do NOT want to end up on the incoming end of this stuff ... period. I suspect people simply dont realise the crazy peak powers these things put out, or that they are 10,000 times brighter than your toy laser pointer, and you don't go staring into that if you are sane either. You won't get chance to blink thats for sure!

As they say .. "Do not stare into beam with remaining eye!"

Ah, you got to love the sound of the old fast flow Trumpf lasers as the roots blower comes up to speed they are a work of art really ... but delicate. I have seen several scrapped because their owners decided to bring them up to full power from cold ... and the chassis twisted as the heat kicked in. since you have 8 mirrors in the folded path to get right, its not a quick or easy job to reallign them. Even when you do get them working, there is still the fun of the plastic connectors on the cooling pipes that go brittle under the high voltage RF etc etc .. but good fun to play with if you can find one going cheap and have the space for it!

The modern ones use a turbo molecular pump, not nearly so much fun
