keyword=Comparison of spin up time with different pumping directionAt 230C oven temperature, with 3 comet laser (75W total power) we did two spin up curves with parallel and anti-parallel pumping. For anti-parallel measurement, it has more points than parallel case. So to treat them unbiasedly, I selected five points from both tests.
The results are the following:
Parallel Pumping:
X Channel Up: 5.2 +- 0.7 hours, 49.6 +- 1.5 mV X Channel Down: 5.0 +- 0.3 hours, 48.5 +- 0.6 mV
Average: 5.03 +- 0.28 hours, 48.65 +- 0.55 mV
Anti-Parallel Pumping:
X Channel Up: 4.7 +- 0.1 hours, 48.2 +- 0.3 mV X Channel Down: 4.6 +- 0.1 hours, 48.2 +- 0.3 mV
Average: 4.65 +- 0.07 hours, 48.20 +- 0.21 mV
