When a 400 uM fiber only fits on a 25 mm or greater scanner aperture, its not so amazing for our purposes.

I should have rented the space under my name for advertising.
When I still could have...
... for a high-power laser-engraving application I've assembled a scanning head with servo-motors instead of galvos and 40mm-mirrors with 5mm thickness ... for me it's cheaper and simpler to control than common galvos ;-)

I wouldn't be planning to scan the beam in the conventional way, Steve.
Yeah, Victor, if I were to scan, it would have to be with huge mirrors like that... for a high-power laser-engraving application I've assembled a scanning head with servo-motors instead of galvos and 40mm-mirrors with 5mm thickness ... for me it's cheaper and simpler to control than common galvos ;-)

.. but I wouldn't scan this beam with X/Y galvos ..
Just to stir this up. If you have a little time, an 8 diode Mitsu P73 module, cooled to an easy -20C and driven at a conservative 10 W would probably be nearly 1/2 as bright as the Dilas module and with a 12mm beam diameter would have MUCH lower divergence than the 400um fiber collimated to the same 12mm diameter beam.
Stir it up Yeah I could combine a bunch of P73s Eric ... nah .. too much trouble :/ Really what I need is a 40W single diode called a P73000000000
Steve,
Just that it would be the size of a Stetson.
Wow. Personally I wouldn't mind that though. Compared to gas ion lasers this is small. Even a Stetson size single diode would be compact in comparison. I'll take one (when they're invented) ..
Really I guess a 40W OPSL is what is needed. Too bad they're so pricey. I wish they made a cheap DIY OPSL kit you put together yourself ..
Lets give our Chinese laser mfg friends that idea
... this 'shoe-box' is roughly 20 years old - this are only 300mW@652nm-diodes!
I have some 50+ of a bit newer (maybe 12 years old) fibercoupled 975nm-diodes with 9Watts each, which (likewise combined) will give something like 400Watts on a spot of maybe 0.5mm, so maybe 200+ Watts out of a 0.4mm-fiber ... too bad, they aren't in the visible range :-/
