摘要： In a method of making a GaAs-based semiconductor laser, a fully processed wafer is cleaved, typically in the ambient atmosphere, into laser bars, the laser bars are loaded into an evacuable deposition chamber (preferably an ECR CVD chamber) and exposed to a H.sub.2 S plasma. Following the exposure, the cleavage facets are coated in the chamber with a protective dielectric (preferably silicon nitride) layer. The method can be practiced with high through-put, and can yield lasers (e.g., 980 nm pump lasers for optical fiber amplifiers) capable of operation at high power.

摘要： The photorecording medium of the invention is formed by mixing a matrix precursor and a photoactive monomer, and curing the mixture to form the matrix in situ. The reaction by which the matrix precursor is polymerized during the cure is independent from the reaction by which the photoactive monomer is polymerized during writing of data. In addition, the matrix polymer and the polymer resulting from polymerization of the photoactive monomer are compatible with each other. Use of a matrix precursor and photoactive monomer that polymerize by independent reactions substantially prevents cross-reaction between the photoactive monomer and the matrix precursor during the cure and inhibition of subsequent monomer polymerization. Use of a matrix precursor and photoactive monomer that result in compatible polymers substantially avoids phase separation. And in situ formation allows fabrication of media with desirable thicknesses.
摘要翻译：本发明的光记录介质是通过混合基质前体和光活性单体形成的，并将该混合物固化以形成基质。在固化期间使基质前体聚合的反应与在数据写入期间光活性单体聚合的反应无关。此外，基质聚合物和由光活性单体的聚合产生的聚合物彼此相容。通过独立反应聚合的基质前体和光活性单体的使用基本上防止了光活性单体和基质前体在固化和抑制随后的单体聚合过程中的交叉反应。使用导致相容的聚合物的基质前体和光活性单体基本避免相分离。并且原位形成允许制造具有期望厚度的介质。
