How bad do you want it?

Unicorn for sale, or pretty close.

A Melles 05-LOR-006 in perfect condition. $650.00

That is a 6" orange 612nm hene laser. (but it is multimode)
Quote from Sam:
  • Orange 612 nm 6" Melles Griot 05-LOR-006 >0.4 mW Random Polarized Multimode: New/NOS Melles Griot ORANGE 612 nm tube, tested. There are probably only a hand-full of working samples of this model remaining in existence. Rated power on these is unknown but is almost certainly under 0.15 mW.

This 10 watt DPSS was marked down to 3600 on ebay: https://www.ebay.com/itm/143599433667

I believe he can sell for less from his web site, it won't be the same model as the ebay listing though, it will be a newer model if purchased direct.

I'm wondering what it is pumped with too, assume 40-50 percent pump efficiency to 1064, then what efficiency for SHG for CW? Prob. about what you are guessing, maybe if they are using a intra-cavity KTP might be higher efficiency requiring a smaller pump.

IINM dpss 532 is only 20-25% efficient overall depending on how efficient the crystal is so yea, likley a 40w 808nm pump, could be a bar type 808nm I never have torn down a 532 that big.

Yes 808 to 1064 then doubled to 532 , it's a 2 part crystal ktp and yvo4 but you know that.

I want to tear one down and look inside, too bad I can't. Anyone ever see the insides of these?

Pfft... I want visible eye candy light, don't have an interest in that kind of thing but it would certainly be fun.

I waited years for this 10W to get down to 3300 USD delivered.

We are going to need lot's of pics and I expect you will employ a large beam expander upon it's Gaussian beam.

It's low price is due to lower specs than a high quality laser, unfortunately, but I will show you what it produces.

Near TEM00, 3-4mm @ 10w sounds good.

What are your plans for it ?

I can't even imagine what 10W of green would look like. I guess DPSS is the only way to achieve that much power. Just think of a portable unit.
