    摘要: A Raman pumping device (10) for amplifying a data optical signal in a fiber optic transmission system, comprising first and second ports (12a, 12b) through which the data optical signal may respectively enter and exit the Raman pumping device (10), a Raman pump source (14) for generating a Raman pump signal, and at least one combiner (16) for combining the Raman pump signal with the data optical signal. The Raman pumping device (10) allows for selectively combining the Raman pump signal generated by the same Raman pump source (14), or at least parts of the same Raman pump source (14) codirectionally or counterdirectionally with the data optical signal.

    摘要: An optical package device includes a first lens which projects, in parallel, an optical signal received from an input optical fiber; a tap coupler filter which delivers an optical signal projected through a first lens to an isolator, and divides the optical signal; a photo diode which senses the divided optical signal; the isolator which fixes a flow direction of the optical signal received from the tap coupler filter; a pump laser diode which generates a pumping light; a wavelength division multiplexer which combines the pumping light and the optical signal passed through the isolator; and a second lens which projects, in parallel, the optical signal combined with the pumping light to an output optical fiber.

    摘要: The disclosure is a method and system for encapsulating components of a fiber laser system. Optical components are placed in a housing, such as a fiber laser block (FB). The housing is filled with a polymerizing encapsulant optionally including a filler. The housing is placed in a vacuum chamber to cause a degassing of interstices created during a filling step. A vacuum is created at a rating level determined by the viscosity of the encapsulant system and the vacuum is released at a rapid rate sufficient to drive the encapsulant into the set of interstices filling the same.

    摘要: An optical amplification mechanism that introduces optical pump(s) into one port of an optical circulator. The optical circulator directs the optical pumps from that port into another port that is coupled to the output of a gain stage. The optical pump(s) then pass from the output to the input of the gain stage while amplifying an optical signal passing from the input to the output of the gain stage. A residual amount of optical pump(s) that exits the input of the gain stage is reflected back into the input of the gain stage. The reflected optical pump(s) then further assists in the amplification of the optical signal. Other embodiments are also disclosed.

    摘要: A method is described for setting up a system comprising an active medium. The method comprises thermally controlling the system comprising an active medium by radiative cooling. The radiative cooling thereby is based on stimulated and/or coherent Raman scattering processes. In particular embodiments, the thermally controlling may be obtained by tailoring the efficiencies of the Raman scattering processes by optimising at least one of a number of system parameters. The invention furthermore relates to systems thus obtained, to methods for thermally controlling systems comprising an active medium that generate radiation and to computer program products for performing the methods for setting up systems comprising an active medium and thermally controlled by radiative cooling using stimulated and/or coherent Raman scattering processes.
