The front end pump diode temperatures were adjusted to increase the laser power.
- D1 was 26.6 degC is now 26.4 degC
- D2 was 24.6 degC is now 24.4 degC
- D3 was 27.8 degC is now 27.5 degC
- D4 unchanged
The temperature changes increased the output power by ~300 mW.
Increased the diode currents for the front end laser to bring the power back to where it should be.
- D1/D2 was 45.5 A is now 46.0 A
- D3/D4 was 47.5 A is now 49.5 A
The net result is that the front end laser power increased by 1 W. That helps to preserve the
injection locking bandwidth a trifle.
The temperatures of the high power oscillator pump diodes was also adjusted. A 4 W increase
was obtained. The diode currents were not touched.
