Latest Patents

One of John Robertson's latest patents focuses on solid state lasers. This invention features an elongate slab of lasing material with a rectangular cross section. The lower face of the slab is in contact with a slab mount made of high thermal conductivity material. Energy to drive the lasing medium is supplied by a flash lamp. The upper and lower faces of the slab are polished to an optically smooth finish, allowing light to propagate in a generally axial direction through the slab. The side faces of the slab are polished and then re-roughened to create a finish with a surface damage zone comparable in depth to the wavelength of the lasing emission. For a lasing wavelength of one micrometer, the depth of surface damage is approximately one micrometer.
