nd:YAG questions

[Laserman532]

i have a 6kw di chiller and a 6kw lamp driver...what the heck, i have a prolase software, galvo driver and the rf driver for the q switch...if you have about 12 k we can have her running in a week

Sure no problems! I have the money transferred to you in a jiff!

Or i take the laser to you and hook it up there to see. Just a little hard to get a 90 pound 6 foot laser as handbaggage though, it will just be to expensive to send it as normal baggage so ill just push it in the plane no matter what they say but the ticket from Sweden with this along would be a little juicy so i dont know..

The laser incl. head, a pretty much unusable software as seems for now, a couple of folders with schematics among other papers, a manual and a huge transport cost of 1/4th the sum due to a transport weight of 120 pounds cost me about 350$ total. Not really happy to pay anymore over this to maybe get some light out from it, effort to get it going no problem bigger amount of money not really but we will see.

Yes it would most likely be a lot easier to control it if it were analog but the protocol used to control it are however a standard one as far as i get it. It named XY2-100 which is quite easy where the position is controlled by a 16-bit number from 0 - 65535 and i have the timing diagram in the manual as well and the contact pin function on the scanhead.

The key could have had a name like that but i think it was something else it was called but dont remember, but never the less very annoying i dont have it and the computer it was most likely attached to had been scrapped.

Buying the remaining components wont happen unless i could get some really cheap because there would otherwise be way way to much money involved for that even it would be second hand and im unfortunately not a millionaire. About if the scanhead works so havent i been able to test it but im quit sure it would be ok, these things handled correctly dont really break.

No, unfortunately no other hardware then on the pictures, only laser and scanhead were included. So if i would like to test the head for example anytime so would it be to either build a psu for it which shouldnt be that hard at all only +-15V @ 3 A max or maybe se if i could find a controlboard if needed or psu on the net. Doubt i will find one however without paying two legs for it, and then maybe some program in a computer to control the scanhed and were on. The small problem is that im not into programming.

YAG rod seems to be fine but the coating on it that isnt visible could i only assume are ok since i dont want to take the rod out and get any dust into the optical path. You might maybe see some very very light dark areas in or on the rod which is when it has been overpowered if im not wrong but its only visible in the flash of the camera sometimes and only then so i dont really know, but it might just be a strange reflection or so.

The optics are pristine as far as i can see, i will not open up the optical path but the mirror in one end that are clear, HR i guess, from one end look as said pristine as well as scanhead mirror.

The only reason this lasersystem was decommissioned were because they had problems with the PSU under the last few years in use and it had been repaired several times the last year for big bucks. The last time it broke down it should cost quite much so they decommissioned the whole system instead. The laser and scanhead was fully working when decommissioned as far he said who was the one that had worked with the system under all the years and the one i bought it from.

Thanks for the answer! You are right and its a CW YAG with a q-switch and that was good to know that its clear to the laser at idle and so it wont be destroyed if i would fire the laser som pulses if possible. Onfortuantly the laser is CW as far as i know about it and what it says on the sign on it.

Im ofcource not scare about the Q-switch neither the lamp or anything else on it, its the laser it self nothing else due to its power. But it was 50% joking about it but also 50% serious as well.

The laser is a 180W CW according to the sign on it and the Q-switch and YAG rod are both water cooled.

Will search for some picture on the computer i have taken on it before to put up some here that might help a little more.

The q-switch is the first one in this link:

Finally found some pictures on it:

Nice laser head. It reminds me of a ND/YAG CW laser I shipped to New Zealand a few years ago. It was made by IE Optomech in the UK.
