H2Oxide, I believe the combination of two Nd:YAG lines at 1064nm and 1319nm will not be nearly as straight forward as your diagram suggests. Spent a lot of time researching it, and the polarity as well as the angles of the two beams will need to be very carefully fine tuned to get a reasonable efficiency.
Would be important to pick a high quality combining mirror too, very high transmission at one wavelength (>99%) and very high reflection at the other (also >99%), otherwise you're going to introduce losses and other problems. Helps that two wavelengths are quite far apart.
