Introduction

L Karsten V Lindström is a notable inventor based in Hagersten, Sweden. He has made significant contributions to the field of laser technology, particularly in the development of methods to create contamination-free laser mirrors. His innovative approaches have led to the filing of two patents that enhance the performance and reliability of GaAs-based lasers.

Latest Patents

Lindström's latest patents include a method to obtain contamination-free laser mirrors and a method for GaAs-based lasers. The first patent describes a technique for achieving contamination-free surfaces on materials such as GaAs, GaAlAs, InGaAs, InGaAsP, and InGaAs at crystal mirror facets for GaAs-based laser cavities. This method involves cleaving the crystal mirror facets and exposing them to an ambient atmosphere, followed by dry etching in a vacuum to remove any oxides and foreign contaminants. A native nitride layer is then grown on the mirror facets through nitrogen treatment.

The second patent focuses on a method using dry etching to obtain contamination-free surfaces on GaAs-based lasers. This process includes placing the laser in a vacuum and performing dry etching with chemically reactive gases or inert gases. A native nitride layer is created using nitrogen plasma, and a protective layer or mirror coating is added to enhance the laser's performance.
