Abstract
System and method for selectively inducing transparency to laser radiation in a material are described comprising a material having a ground state and two closely-spaced first and second excited states wherein the transition dipole moment d.sub.1 between the ground and first excited states is parallel to the dipole moment d.sub.2 between the ground and second excited states, and wherein d.sub.1 is substantially equal to zd.sub.2 where z is a scalar constant characteristic of the material, and wherein the frequencies of transition between the ground and first excited states and between the ground and second excited states are .omega..sub.o and .omega..sub.o +.DELTA., respectively, and a source of laser radiation for substantially totally irradiating the material with laser radiation of frequency .omega..sub.L substantially equal to .omega..sub.o +.DELTA./(1+z.sup.2).
