Setup history
Plano-Concave High-Reflectivity mirrors
The reference of the cavity mirrors with wedge substrats is :
- xx — xx — xx
Plano-Concave with wedge mirrors
The reference of the cavity mirrors with wedge substrats is :
- LW-1-2037-UV from CVI-Melles Griot. It means :
- large window — 1° wedge — 2in diameter 0.375 in base — fused silica (n=1.45@1064nm)
The reflectivity of the coating of the first set of mirrors with wedge C080 76/2, C080 76/3, C080 76/4 and C080 76/5 was too high (see logbook entry 68). A second set of mirrors was coated with the right specifications C081 00/2, C081 00/3, C081 00/4 and C081 00/5 :
Plano-concave recycling mirrors
The reference of the recycling mirrors substrats is :
- SMCC-2037-27.0-C from CVI-Melles Griot. It means :
- Concave Spherical Mirror Blanck — 2 in diameter 9.52mm thickness — 27m of radius of curvature — N-BK7 (n=1.51@1064nm)
note: coated by LMA. Mirror’s backside has been coated antireflective @1064 nm.
Recycling cavity peak off
The reference of the recycling cavity peak off is :
- LW-1-2050-C from CVI-Melles Griot. It means :
- Large Wedge window — 1° wedge — 2 in diameter 12.7mm thickness — N-BK7 (n=1.51@1064nm) and no coating (or by LMA?)
Sampling mirrors
1064 line
The reference of the Rmax@1319 dichroic mirror used on the 1064 line is
- SWP-45-RS1319-TP1064-PW-1025-C from CVI-Melles Griot. It means :
- Shot Wave Pass — Rmax S@1319 — Tmax P@1064– ?? — 2in diameter 0.25in thickness — N-BK7
