measured PMC's laser power-output relation |
|

(Rana, Yuta)
Motivation:
We wanted to see thermal effects on the PMC.
What I did yesterday:
Changed the current of the NPRO from 2A to 0.8A and measured the power of the reflected/transmitted light from the PMC when locked.
I also measured the power of the reflected light when PMC is not locked (It supposed to be proportional to the output power of the laser).
Result:
Attached. Hmmmm......
At several points of the laser current, I could'nt lock the PMC very well. The power of the reflected/transmitted light depend on the offset voltage of the PZT.
When the laser power was weak(~<0.9A), the power of reflected/transmitted light changed periodically(~ several minutes). |
