Alice Renaux | Under Process | report | lasers and optics | Optical room | Finesse measurement | Today, with Ronic, we measured the finesse
of the 2-mirror cavity witht the NKT CW laser.
We were able to perfrom the measurement |

Alice Renaux | Under Process | report | lasers and optics | Optical room | Finesse measurement | (Finesse 2651 is consistent with that obtained
from the mirrors' transmission coefficients,
which is about 3100.) |

Alice Renaux | Under Process | report | lasers and optics | Optical room | new cavity | The 2-mirrors cavity has 460ppm of transmission
for M1 and 10ppm for M2 which should exhibit
a Finesse around 13400. |

Ronic Chiche | Under Process | info | mechanics | lasers and optics | cabling | Optical room | Neolase amplifier installation | we have all the adaptor plugs for connecting
the chiller.
so, I tested first the chiller connected |

Ronic Chiche | Under Process | info | mechanics | lasers and optics | cabling | Optical room | Neolase amplifier installation | now, I connected the chiller circuit to
the amplifier, thanks to the adapters.

Ronic Chiche | Under Process | info | mechanics | lasers and optics | cabling | Optical room | Neolase amplifier installation | pipes are maybe too long ?
we can use the Darcy-Weisbach +
Blasius laws (non linear laws). |

Ronic Chiche | Under Process | info | mechanics | lasers and optics | cabling | Optical room | Neolase amplifier installation | I drained the chiller to install again
the short pipe (< 1m) in closed loop.
then, I filled again the chiller |

Ronic Chiche | Under Process | info | mechanics | lasers and optics | cabling | Optical room | Neolase amplifier installation | now, I installed the long pipes (2x 3m)
in closed loop (without the amplifier connected),
but the exact ones used to connect the laser, |

Ronic Chiche | Under Process | info | mechanics | lasers and optics | cabling | Optical room | Neolase amplifier installation | I cut a small part of the black pipe on
the amplifier side (could it be slightly
deformed by a try with an other type of adapter |

Ronic Chiche | Under Process | info | mechanics | lasers and optics | cabling | Optical room | Neolase amplifier installation | as soon as I connect the amplifier to the
pipes, the flow decreases to 1.7Lpm.
and the filling process is very |
