    ... hmmm ... my high-power IR-diodes, already focussed or fiber-coupled are mostly salvaged from broken fiberlasers or "random finds" at ebay and in the range of 50 to 300 Euros - you can see some of them here:

    Was testing and developing with all sorts of diodes (NIR and VIS) in the last years ... actual best bet are the 200W and 270W@975nm diodes with internal focussing on a spot of 0,2mm ...

    It depends on your needs, of course. I also tried to ground the price to reasonable limits. Considering the diodes have most of their lifespan intact and the watercooled power supplies in a matching set that would run for an all be it crazy price of 25K EUR replacement for the CTP machines they are from. However, price is not set in stone. Make an offer and let's work something out. Always opened to negotiations.
