Sweet deal on 50W DPSS pumping modules.

These are pretty pricey, but for what you're getting they're en excellent deal:

50+W of 1064nm output. Run that through a suitable SHG crystal and you've got yourself one HELL of a greenie..

I'm not sure too many people here would be in the market for one of these, but I thought I'd post it anyway, just in case..

You weren't kidding about it being pricey but no boubt you'll get what you pay for

 

[ElektroFreak]

Considering they contain a sizeable Nd:YAG rod and several 20W pump arrays, $2500 brand new is truly a steal.

I've been eyeballing those for a while now :beer::beer:

To get a decent amount of green, you will need a bit more then just this.
You will also need a polarizer plate, q-switch and driver, and a telescope cavity, with non flat mirrors, so you get a beam waist inside the SHG crystal, not to mention the oven and temperature control for the KTP.

At least in theory, it's not like I did all that myself

^you're definitely right.. but it would still be quite possible to build a high-end 5-8W 532nm system for a bit less than the $10,000-$25,000 that they usually cost new..

I just assumed that anyone willing to drop $2500 for one of these would already know the basics of how to build such a system..

I agree with 99% of that, the 1% being that it could be done without a q-switch :yh:

Hell, if you wanted to be really sloppy you could get a decent amount of green with a flat HR and an OC with the appropriate ROC, slap the KTP in there and heat it up until you get good power. Obviously not the most efficient way to do things, but you would get green!

BUT, if you want killer power, obviously you would want to q-switch it and set up a much more efficient cavity. V cavity or Z-fold etc etc

Note the lack of a q-switch.
BTW, I don't own this laser. The images are originally from junktronix's site.

I love seeing labbies like that running. Nice photos.
