The passive enhancement of coherent laser light in an optical resonator leads to a power increase of a few orders of magnitude, which can be used e.g. to increase the conversion efficiency of nonlinear optical processes and/or to an increased sensitivity to absorption and chromatic dispersion, which can be used for metrology.
Working principle of an enhancement cavity: the pulses of a MHz-repetition-rate train are coherently added up in time to a significantly more intense pulse circulating in the cavity. The cavity consists of an input coupler (R < 100%) and several highly reflecting (HR) mirrors (R=100%).
