We report on the frequency locking of a frequency doubled Nd:YAG laser to a45 000 finesse, 87-cm-long, Fabry-Perot cavity using a modified form of thePound-Drever-Hall technique. Necessary signals, such as light phase modulationand frequency correction feedback, are fed direcly to the infrared pump laser.This is sufficient to achieve a stable locking of the 532 nm visible beam tothe cavity, also showing that the doubling process does not degrade laserperformances.
