  • Laser active medium and process of manufacturing the same
    Patent number: 10559936
    Abstract: A solid-state laser active medium comprising an optical gain material; a heat sink, wherein the heat sink is transparent, in particular over a wavelength range of 200 nm to 4000 nm, preferably with an absorption coefficient of <1 cm?1; the heat sink having a high thermal conductivity, in particular ?149 W/(m*K); wherein the optical gain material and the heat sink exhibit a root-mean square, RMS, surface roughness of <1 nm; wherein the optical gain material is attached to the transparent heat sink by direct bonding.
    Type: Grant

  • Substrate transferred monocrystalline bragg mirrors
    Patent number: 9945996
    Abstract: A mirror assembly comprising a carrier substrate; a stack comprising a plurality of alternating monocrystalline semiconductor layers of a first and a second type, wherein the layers of the first type have an index of refraction higher than the layers of the second type thereby forming a Bragg mirror; wherein the carrier substrate is curved having a radius of curvature between 0.1 m and 10 km; wherein the stack is attached to the curved carrier substrate.
