摘要： Systems and methods for providing laser texturing of solid substrates are disclosed. The texturing may be used to provide grayscale images obtainable from substrates, which may include steel, aluminum, glass, and silicon. In some embodiments, images may be obtainable from the substrate by modifying the reflective, diffractive, and/or absorptive features of the substrate or the substrate surface by forming random, periodic, and/or semi-periodic micro-structure features on the substrate (or substrate surface) by an ultrafast laser pulse train. The ultrafast pulse train may be modulated in order to vary, for example, optical exposure time, pulse train intensity, laser polarization, laser wavelength, or a combination of the aforementioned. The ultrafast pulse train and the substrate may be scanned with respect to each other to provide different optical energies to different regions of the substrate (or substrate surface). In some embodiments, the image is provided by making one or more passes of the ultrafast laser pulse train relative to the substrate.

摘要： Embodiments of parametric chirped pulse amplifiers seeded with a single pulse source which is subsequently split into a signal arm and a pump arm with appropriate signal and pump conditioning stages are disclosed, which advantageously improve the utility of high average power and/or high energy ultrafast amplification systems. In various embodiments, at least one of the signal or the pump conditioning stages is non-linear, allowing for a great range of seed sources to be utilized. Chirped pulse amplification in the pump conditioning stage may be used to simplify the parametric amplification of pulses with pulse widths of the order of 10 fs. The parametric pump can include coherently combined fiber arrays, hybrid fiber solid-state amplifiers, and/or cryogenically cooled solid-state amplifiers to increase or optimize the energy extraction of high average powers.

摘要： Double clad large mode area planar lasers or amplifiers comprising rare-earth or transition metal doped planar core regions are used to generate near-diffraction-limited optical beams of ultra-high power. The amplified light is guided in the core using different guiding mechanisms in two orthogonal axes inside the core. Waveguiding along a first long core axis is obtained substantially by gain-guiding or thermal lensing. Waveguiding along a second short core axis is obtained by index guiding. This is accomplished by surrounding the planar core region with regions of different refractive index. The long sides of the planar core region are surrounded with a depressed refractive index cladding region. The short sides of the planar core region are surrounded with a cladding region substantially index-matched to the core region. The whole structure is surrounded by an outer cladding region with a low refractive index to enable cladding pumping of the planar waveguide with high-power diode lasers. The rare-earth or transition metal doping level inside the planar core can be constant and can also vary substantially without negatively affecting the waveguiding properties. To avoid bend losses along the long axis of the planar waveguide, the planar core region and the planar waveguide are aligned parallel to each other and the planar waveguide is coiled with the long side of the planar waveguide mounted to a drum. The drum can also be used as a heat sink. A planar waveguide comprising a planar core region can be manufactured using conventional fiber fabrication methods.

摘要： An optical beam shaping element is used to produce a beam of high brightness from a diode bar or a single emitter diode, allowing for efficient coupling of the beam into an optical fiber. An embodiment of the beam shaping element allows the construction of a quasi-monolithic or truly monolithic beam shaper incorporating both fast axis collimation as well as beam rotation. Additional slow axis collimation or collimation of the beam-rotated fast axes of the individual emitting elements of the diode bar is also possible in one quasi-monolithic or truly monolithic design. The beam rotation element comprises an array of beam-inverting planar grin lenses aligned with their axes of equal refractive index at an angle of ±45° with respect to the slow axes of the emitters. Alterative embodiments comprise beam rotation elements based on two planar grin lens arrays, arrays of uniaxial grin lenses, arrays of uniaxial focusing reflective optic or arrays of cylindrical Fresnel lenses. The beam shaping element can be used in conjunction with stacks of diode bars or alternatively optical beams of ultra-high power can be generated by combining multiple fiber coupled diode bars in a fiber bundle incorporating metallization and a heat sink.
