These Diffusion Bonded composite crystals
are used to effectively decrease heat effect of Solid-State
High-Power Laser.
 high damage threshold
improve beam quality
decrease thermal effect
improve efficiency
compact size
Composite laser rod is a crystal consisting
of two, three or more parts with different dopant level.
Usually, doped and undoped material used.
Dopant level and rod configuration can vary as well as the
number of parts. It can have different wedged structure,
Brewster angles, etc.
