  • Laser stress mitigation for heat-assisted magnetic recording
    Patent number: 11404083
    Abstract: An apparatus has a substrate. A laser is deposited above the substrate. The laser comprises one or more non-self-supporting layers of crystalline material. A first layer is disposed proximate the laser. The first layer is deposited using a first process. A second layer is disposed proximate the second layer. The second layer is deposited using a second process different than the first process. The first layer and the second layer are configured to mitigate mechanical stress in the laser. A waveguide is deposited proximate the laser. The waveguide is configured to receive plasmons from the laser and direct the plasmons to a recording medium.
