In post #24 are you saying the Yb:YAB crystal's lasing at 1016nm, 1090nm and 1125nm? I took the quote as those being the pump wavelengths and the lasing lines were 510nm and 530nm. It sure seems that those are pump wavelengths to me and much too high to be a candidate for the 575nm crystal or the 565nm crystal.
That's why I stated it with a caveat. But this second article uses a 976 nm diode "Self frequency doubling ytterbium laser" to see why Curtis and me think this is some type of ytterbium laser.
