crystals are used to generate laser radiations.
The commonly used laser crystals include Nd:YAG,
Nd:YVO4 and Nd:YLF for near IR lasers, and Ti:Sapphire
for tunable near IR output. Specifically, Nd:YVO4,
diode pumped solid state lasers were developed
because diode pumping attracts more and more interest
of both R&D and OEM customers.

||A piezoelectric transducer
is bonded to an anisotropic medium. When an electrical
signal is applied to this transducer to generate
waves which are propagated through the
medium, a three dimensional
grating was formed by
virtue of refractive index variation associated
the traveling acoustic wave. The incident beam
passing through the
medium will be coupled into
several symmetrical diffraction orders, just
in a two-dimensional diffraction grating.
There are two kinds of E-O modulations. One is longitudinal
modulation if the directions of electric field
and light propagation are the
same. The KDP isomorphic
crystals are normally used in this scheme.
