METHOD AND DEVICE FOR MEASURING LIGHT ENERGY ABSORPTION AMOUNT, AND METHOD AND DEVICE FOR CONTROLLING THE LIGHT ENERGY ABSORPTION AMOUNT

摘要

PROBLEM TO BE SOLVED: To make a light absorber inserted into an optical resonator absorb light energy stored in the optical resonator, to measure the light absorption amount at high sensitivity, and to control the light absorption amount with high accuracy.;SOLUTION: In making the light absorber inserted into the optical resonator absorb the light energy of a stationary wave shape stored in the optical resonator, the light absorption amount can be measured with high sensitivity by positioning the light absorber at wavelength accuracy. In making the light absorber inserted into the optical resonator absorb the light energy of the stationary wave shape stored in the optical resonator, the light absorption amount by the optical resonator can be controlled with high accuracy, by positioning the light absorber sufficiently thinner than the wavelength of the incident light at wavelength accuracy.;COPYRIGHT: (C)2007,JPO&INPIT
