561nm Yellow YAG (?) from Lumenis Varia Eye Laser

Here is a photo from the 561nm "yellow" section of a Lumenis Varia Tri-Color Laser, the machine this element came out of was rated at 600mw of yellow output.



Photo of what appears to be a YAG from this section:



I believe this crystal is a square YAG which appears to be side diode pumped, if that is what it is, does anyone here know if these can be pumped with a common IR bar diode? The photo appears to show the crystal is being directly pumped that way but at what wavelength?

Edit: Lumenis calls 561nm "yellow" but it looks more green than yellow to me: Lumenis Novus Varia Red, Yellow, Green Tri Laser System | Laser Locators
