  • Patent number: 11108209
    Abstract: Stimulated Brillouin scattering (SBS) limits the maximum power in fiber lasers with narrow linewidths. SBS occurs when the power exceeds a threshold proportional to the beam area divided by the effective fiber length. The fiber lasers disclosed here operate with higher SBS power thresholds (and hence higher maximum powers at kilohertz-class linewidths) than other fiber lasers thanks to several techniques. These techniques include using high-absorption gain fibers, operating the laser with low pump absorption (e.g., ?80%), reducing the length of un-pumped gain fiber at the fiber output, foregoing a delivery fiber at the output, foregoing a cladding light stripper at the output, using free-space dichroic mirrors to separate signal light from unabsorbed pump light, and using cascaded gain fibers with non-overlapping Stokes shifts. The upstream gain fiber has high absorption and a larger diameter for high gain, and subsequent gain fiber has a smaller diameter to improve beam quality.

  • Patent number: 9223933
    Abstract: Certain examples provide systems, methods, apparatus, etc., to generate formlets for user review of and interaction with clinical data and associated functionality for one or more patients. An example method includes receiving one or more query criterion to retrieve data and generating a query result of data from one or more data stores based on the one or more query criterion. The example method includes applying a transform to the query result data. The example method includes applying a data template and binding instructions to the transformed query result data to generate a formlet including data and at least one of associated relationship and functionality information for display of and interaction with the data. The example method includes facilitating runtime configurability of the formlet by a user. The example method includes displaying the formlet for user review and interaction.
