    The donut diode rings are each 100 watts, I believe this is likely DC watts into the diodes, three 100 watt rings producing 300 watts at 50% efficiency would be 150 watts of IR pump power, so it stands to reason the output of the ND:YAG is 1/3, or 50 watts, perhaps 60. Is my reasoning valid?

    You could get 120+ watts out of one single ND:YAG from the Avia Thor when pumped at 300 watts? Impressive, especially 150W. Just wanted to confirm this is possible from a three diode ring Avia Thor ND:YAG, thanks.
