Hi Over there,
I'm just here trying to repair my old 60Ws YAG laser engraver. A new stack was told to be in the 5000 Bucks range by the manufacturer.
Quite a lot of money for the bonding of 400 Dollars of Diodes and some grams of brass for the mcp coolers - for a more or less hobby unit.
The laser source is made by the german manufacturer photon energy. I have s second unit as well, wich was totally filed with water. This laser as well leaked, I just disassembled everything and started to reassemble it in an flowbox.
Because the Diodes were bad, i've got me some similar diodes from an old foba -Laser and assembled them from two 2 Bar Stacks to a 4 bar stack.
Unfortunatly I've touched a front facette while mounting.
Are there any hints to spray clean the front facetes - just to "degrease" them.
Are ther some expierences and dont`s ?
On a datasheet from osram they state that the diode facettes can't be cleaned anyway - but maybe cleaning is better than a burning diode.., these diodes are Jenoptik, the old ones were probabky some of a manufacturer from Swizerland.
Any hint may be helpful
Best regards
P.S. If somebody would have some used MCP cooled 808nm Diodes - with two small appx. 4mm dioameter cooling holes in the unterside, smaller than the normal jenoptik MCP cooled diodes - I would be really happy about an offer. Suited protection googles on hand here - also for pumping wavelength.
