Abstract: Single heterogeneous crystals are described that contain multiple regimes, adjacent regimes varying from one another with regard to function. Also disclosed is a hydrothermal epitaxial growth process that can be utilized to form the single heterogeneous crystals. The single heterogeneous crystals can exhibit enhanced performance when used as a laser gain medium as compared to previously known single crystals and multi-crystal constructs. The heterogeneous single crystal can be utilized for thin disk lasers and can minimize the thermal distortion effects at high powers. The heterogeneous crystal can also serve as an embedded waveguide.

Abstract: Single crystals are described that contain several regimes within the crystal that perform different functions related to the enhanced performance of a laser gain medium. At least one regime of the single crystals can be utilized to suppress amplified spontaneous emission and parasitic oscillation in a laser gain medium. A single crystal can include core and cladding regions, the cladding region providing amplified spontaneous emission suppression. The core region of the crystal can include as dopant one or more ions that take part in the lasing when suitably pumped. The amplified spontaneous emission suppression region can include as dopant one or more ions that can prevent additional spontaneous emission that can to depletion of the upper laser states, thus reducing laser performance including one or more ions that absorb spontaneously emitted photons and/or a higher concentration of the active lasing ions of the core.
