Things to Think About

  1. What are the problems involved in using a double demodulation scheme? How is it related to cavity macroscopic length?

How to use LISO

  • The linux version of LISO is in the directory /home/stochino/alberto40m/liso/filter of my computer.
  • I modified the fil.ini file so that the gnuplot path matches with that of my computer.
  • To run LISO one has to be in the directory where the liso.linux binary file and the fil.ini file are.

  • From that directory, just call ./liso.linux <.fil file>, where the ".fil" file is the one that contains the netlist.

Lower Finesse for 40m Upgrade/Advanced LIGO

The losses are usually not well known. A lower finesse has less sensitivity to optical losses in the mirrors. Why?
