摘要： Optical systems operable to emit an output beam having fast-switched wavelengths are provided. In one embodiment, an optical system includes a laser and a wavelength conversion device. The laser emits a pump beam that switches between at least two fundamental spectral peaks at different wavelengths at a wavelength cycling period that is shorter than a response time of the human eye. The wavelength conversion device includes a non-linear optical medium configured to phase match the frequency doubling of the at least two switched fundamental spectral peaks such that an output beam that switches between at least two frequency-converted spectral peaks at different converted-wavelengths is emitted from an output facet of the wavelength conversion device when the pump beam of the optical source is incident on an input facet of the wavelength conversion device.

摘要： An optical fiber for performing pulse stretching, and fiber laser systems and methods using the pulse-stretching fiber are disclosed. The pulse-stretching (PS) fiber has low fourth-order dispersion (dispersion curvature) and a third order dispersion (dispersion slope) with a small negative, nearly zero or small positive value. Two different types of fiber laser systems that use the PS fiber in a manner that achieves optimum performance are described. The PS fiber enables an all-fiber (up to the final pulse compressor) ultra-short pulsed laser systems reaching pulse energies exceeding 100 μJ, average powers exceeding 100 W, and output pulse widths of less than 100 fs.
