Tonight we saw ETMX 15007 Hz MODE 18 ring up almost immediately upon increasing power to 50 W. It damped with no problems with -1k damping gain, no phase. Active damping for this mode has been added to the SUS_PI guardian. First attachment shows ring up and subsequent damping. 

Not sure why this mode didn't ring up last night; the only thing that's different is that last night Kiwamu babysat the ITMX CO2 laser power. Second attachment shows last night, third attachment shows tonight. Upon arriving at 50 W last night, the CO2 power was ~0.08 W, versus tonight the power was ~0.39 W. However, SRC and PRC gouy phases are both very similar at that time.
