I may have to opportunity to pick up some Lightwave Half-Note lasers. If you're not familiar with these, they are 2-3W CW 532nm and use a single 20W pump diode that can be replaced without needing to realign the cavity. They have a built-in driver, but the interface is non-trivial. If I get several of them, I'd spend the time to come up with a simple control panel. They support analog modulation, but probably not very fast. If you wanted to make your own driver, you'd need a 10A TEC driver for the baseplate, a 1.5A TEC driver for the KTP and a 25-30A diode driver for the pump diode.
As for pricing, they'd be around $1K for units making >2W and a bit more for units making >2.5W.
I've attached a bunch of pictures of one of these units. Note that the control panel shown (labeled halfnote test fixture) is not going to be included.
