Document type:

G - Presentations (eg Graphics)

Abstract:

The diode laser in the oplevs can be fixed and stays fixed. There are possibly other problems with the oplevs such as spot size and shape and QPD quadrant responses etc. This presentation describes the laser fix and the laser behaviour before and after.
