Abstract: Embodiments relate to a high power supercontinuum (SC) fiber optical source. The SC fiber optical source includes a prebroadening optical fiber that broadens the spectrum of a lower power intermediate optical signal before final amplification. The spectrum broadening creates spectral components which facilitate further spectrum broadening of amplified signal in final nonlinear stage, allowing to achive flatter and wider spectrum, and reduces nonlinear Stimulated Brillouin Scattering (SBS) that could damage SC fiber optical source components or limit the output power of the SC fiber optical source signal, thus enabling higher output power. After amplification in booster, passing at least part of broadened spectrum, the optical signal spectrum is further broadened by injecting the optical signal into a nonlinear stage to create a SC optical signal.

Abstract: Systems and methods of enabling a service level agreement to specify interactions between an application and a remotely located object store that manages data as objects. A computing device receives data associated with a request to write application data to an object store according to a schedule, wherein the data is file system data. The computing device creates a snapshot associated with the requested application at a snapshot pool, and transmits instructions to a cloud formatting engine to create a virtual disk at a storage pool associated with an object store. The computing device copies the snapshot from the snapshot pool to the virtual disk, the snapshot comprising file system data and transmits instructions to the cloud formatting engine to convert the data associated with the first snapshot into an object, and move the object from the virtual disk to the object store.

Abstract: A beam position measuring apparatus and method using a beam expansion device may expand areas of beams irradiated onto a beam detection sensor. The beam expansion device is configured to expand areas of the beams onto the beam detection sensor is installed between a beam generator and the beam detection sensor. Central positions of the irradiated beams are detected using intensities of beams irradiated onto respective pixels of the beam detection sensor.
