589nm and 593.5nm are not diode lasers. They are DPSS systems that are very expensive. They will need a fully custom host with an external lens of a diameter of roughly 1/2 inch spaced around 40 - 50mm from the module end. They will require a lot of work indeed. Right now you can get a 589nm module for 1300 dollars and the host will be another 100-150 dollars.
