NKT Photonics large mode area, Photonic Crystal Fiber (PCF) ESM-12B
sourced from ThorLabs. This is a fiber under consideration for higher power, lower loss, green light injection for the OPO in the squeezer subsystem. |

Thu Jan 17 16:04:17 2019, Dennis Coyne, General, General, revised thermoelastic response of the cavity mirror
|
The original thermoelastic response of the mirror was documented in T970212, using the IDEAS finite element
code. The analysis was redone using ANSYS and an analytical (series expansion); These two approaches agree with each other fairly well. The new results
are similar to the original steady-state calculations in the original T970212-x0. The new results are uploaded to T970212-v1. While the characteristic |

Wed Jan 2 12:06:43 2019, Dennis Coyne, General, General, Current status/state of the Optical Contamination Facility (formerly OTF)
|
The Optical Contamination Facility (formerly the OTF, Optical Test Facility) consists of 3 vacuum chambers with high-finesse, resonant optical
cavities used to test the effect of outgassing from materials/assemblies on optical properties (absorption, scatter @1064nm) over time.
