Picosecond and nanosecond pulse delivery through a hollow-core Negative Curvature Fiber for micro-machining applications.
We present high average power picosecond and nanosecond pulse delivery at 1030 nm and 1064 nm wavelengths respectively through a novel hollow-core Negative Curvature Fiber (NCF) for high-precision micro-machining applications. Picosecond pulses with an average power above 36 W and energies of 92 µJ, corresponding to a peak power density of 1.5 TWcm⁻² have been transmitted through the fiber with...
متن کاملCompression of Femtosecond Optical Pulses Using Hollow-Core Fibers
Fused-silica and silver-coated hollowcore fibers have been used to compress femtosecond optical pulses from a Ti:sapphire laser at 800 nm. Input pulses with energy of 250 μJ and duration of 110 fs were used and compressed pulses with duration of 20 fs and energy of 220 μJ were generated by using the silver-coated fiber. When a similar uncoated fused-silica hollow fiber was used, compressed puls...
متن کاملSpectral attenuation limits of silica hollow core negative curvature fiber.
In this paper we discuss the limits of attenuation of silica hollow core negative curvature fibers in the wavelength range from 800 nm up to 4.5 µm. Both numerical and experimental results are presented and show good agreement. A minimum attenuation of 24.4 dB/km was measured at around 2400 nm wavelength, while 85 dB/km was measured at 4000 nm.
متن کاملDispersion properties of high-contrast grating hollow-core waveguides.
We present unique dispersion characteristics of high-contrast grating (HCG) hollow-core waveguides and show that slow light can be facilitated using internal resonances developing inside the waveguide walls. In addition, we show a fast and precise method of inferring the dispersion information from the waveguide angular reflectivity spectrum.
متن کاملStrong Light Localization and a Peculiar Feature of Light Leakage in the Negative Curvature Hollow Core Fibers
In this paper we would like to continue a discussion started in our previous work and devoted to the mechanism of light localization in hollow core microstructured fibers with a noncircular core-cladding boundary. It has been shown in many works that, for waveguide microstructures with different types of core-cladding boundary shape, the positions of the transmission bands’ edges can be predict...
