Abstract:
We have investigated the generation of highly pure higher-order
Laguerre-Gauss (LG) beams at high laser power of order 100W, the same regime
that will be used by 2nd generation gravitational wave interferometers such as
Advanced LIGO. We report on the generation of a helical type LG33 mode with a
purity of order 97% at a power of 83W, the highest power ever reported in
literature for a higher-order LG mode.
