The glass article is desirably responsive to actinic radiation, such as being capable of demonstrating a change in refractive index upon exposure to actinic radiation. The film permits passage of the actinic radiation. through the film and into the substrate. In specific implementations, the film comprises at least about 30 atomic percent carbon, from about 0 to about 50 atomic percent silicon, and from about 0 to about 50 atomic percent oxygen on a hydrogen-free basis.

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： The present invention generally concerns the use of Bragg optical fibers in chirped pulse amplification systems for the production of high-pulse-energy ultrashort optical pulses. A gas-core Bragg optical fiber waveguide can be advantageously used in such systems to stretch the duration of pulses so that they can be amplified, and/or Bragg fibers can be used to compress optical signals into much shorter duration pulses after they have been amplified. Bragg fibers can also function as near-zero-dispersion delay lines in amplifier sections.

摘要： In an optical amplifier, passively wavelength-stabilized pump diodes generate pumping light to excite a gain medium (e.g., rare-earth-ion doped optical fiber or solid-state optical amplifier) near an absorption peak of the gain medium. The gain medium amplifies a pulsed laser signal coupled into the gain medium to a high peak power with minimal non-linear distortion. The gain medium may include a portion configured to receive the pumping light and another portion configured to amplify the pulsed laser signal. A volume phase hologram device may passively wavelength stabilize the pump diodes by reflecting a portion of the pumping light back to the pump diodes. Passively wavelength-stabilizing the pump diodes improves power efficiency of the optical amplifier.
