摘要： Systems and methods for producing ultra-short optical pulses are provided. According to various embodiments, optical pulses are generated, stretched, amplified, and compressed to ultra-short lengths. In order to achieve the ultra-short lengths, dispersion compensation is provided prior to amplification and optionally before compression. Dispersion compensation prior to amplification can be performed by passing the optical pulses through a polarization-maintaining fiber that includes a nonlinear Bragg grating. In some embodiments, the optical pulses are repeatedly circulated through the polarization-maintaining fiber that includes the nonlinear Bragg grating. Dispersion compensation before compression can be achieved by passing the amplified optical pulse through another length of polarization-maintaining fiber.

摘要： A semiconductor gain-structure functions as a gain-element in a laser-resonator. The gain-structure is bonded to a diamond heat-spreader that is peripherally cooled by a heat-sink configured to allow access to the gain-structure by laser-radiation circulating in the laser-resonator. In one example, the gain-structure is used as a transmissive gain-structure in a traveling-wave ring-resonator. In another example, the gain-structure surmounts a mirror-structure which functions as an end-mirror of a standing-wave laser-resonator.
