In one embodiment, the instant invention is an optical structure that includes: an optical active medium of a solid state laser, where the optical active medium has a first coefficient of thermal expansion; and a protective structure that is directly cladded a portion of the optical active medium, where the protective structure has a second coefficient of thermal expansion which matches the first coefficient of thermal expansion of the optical active medium, and where the protective structure is transparent to a wavelength that is within an absorption band of the optical active medium so that the optical structure has: the optical active medium that is protected from a physical damage, and the optical active medium that is capable of generating a laser beam having a first energy that is larger than a second energy generated by a control optical structure having the optical active medium without the protective structure.
