Vm. Garmash et al., MEASUREMENT OF ABSORPTION LOSSES IN MIRRORS OF LASERS WITH INTRACAVITY FREQUENCY-DOUBLING, Kvantovaa elektronika, 20(3), 1993, pp. 244-246
Absorption losses in mirrors of a laser operating in the intracavity f
requency transformation regime is investigated by means of phototherma
l radiometry. An increase of the mirror absorption coefficient at the
main wavelength has been revealed, when the second harmonic radiation
is incident on the mirror. The photoinduced absorption depends on the
coating type and intensity of this influence.
