Laser is back (sort of) |

Yoichi, Peter, Jenne
Summary:
We found that the chiller water is not going to the NPRO base. It was hot whereas it was cold when I touched it a few months ago.
I twisted the needle valve on the water line to the NPRO base. Then we heard gargling noise in the pipe and the water started to flow.
The laser power is now climbing up slowly. The noisiness of the MOPA output is reduced.
I will post more detailed entry explaining my theory of what actually happened later. |
