摘要	In various embodiments, laser systems feature beam emitters thermally coupled to heat sinks comprising, consisting essentially of, or consisting of a metal- matrix composite of a thermally conductive metal and a refractory metal. At least a portion of the surface of the heat sink is treated to form a depleted region, and a diamond coating is deposited within and/or over the depleted region. The depleted region is substantially free of the thermally conductive metal or contains the thermally conductive metal at a concentration less than that of the body of the heat sink.
其他摘要	在各种实施例中，激光系统的特征在于热耦合到散热器的光束发射器，其包括，基本上由导热金属和难熔金属的金属 - 基质复合物组成，或由其组成。处理散热器的至少一部分表面以形成耗尽区域，并且在耗尽区域内和/或上方沉积金刚石涂层。耗尽区域基本上不含导热金属或包含浓度小于散热器主体浓度的导热金属。
主权项	A method of heat sink preparation, the method comprising: providing a heat sink comprising a metal-matrix composite of a thermally conductive metal and a refractory metal; etching at least a portion of a surface of the heat sink to form thereon a depleted region comprising the refractory metal and being substantially free of the thermally conductive metal; and depositing a coating comprising diamond over the depleted region.
