Bram, Alberto, Elli. We set the green laser doubler crystal temperature to maximise the green laser power output. The laser diode current was 1.725A and the 1064 laser crystal was 42.05 degrees C. We varied the doubler crystal temperature and measured the power output. Attached is a plot of these measurements. The green laser power was maximised when the doubler crystal temperature was set to 34.37 degrees C.
When the doubler crystal temp was 34.37 degrees C:
(with 1.725A input current, 42.05 degrees C crystal temp)
-The laser power output was measured at 41.9mW
-GR_PWR_MON read 8400 counts
-REFL_PWR_MON read 15500 counts, and we measured 1.22mW, 4.8V, and a gain setting of 20dB at this PD.
