Diffusion
Bonded Composite
Crystals
Diffusion
Bonded Composite
Crystals consist
of one laser
crystal and one
or two undoped
material. They
are combined by
optical contact
method and
further bonded
under high
temperature.
Diffusion Bonded
Crystal helps to
decrease thermal
lensing effect
considerably.
