Composite laser array support

摘要

Nonmonolithic laser arrays having lasing elements mounted on a composite support that enables accurate positioning and separation of the lasing elements, and that enables low thermal, optical, and electrical cross-talk. The support includes a low thermal diffusivity region surrounded by high thermal diffusivity regions which have defined mounting surfaces onto which the lasing elements mount. Heat generated in the lasing elements is conducted away by the high thermal diffusivity regions, while the low thermal diffusivity region reduces thermal cross-talk between the lasing elements. Beneficially, the support assists current flow to (or from) the lasing elements.
