Compression of femtosecond pulses in a wide wavelength range using a large-mode-area tapered fiber
摘要： We report the design of a tapered fiber that can be used for the compression of pulses at different central wavelengths. The proposed fiber is a three-layer W-type large-mode-area fiber, which has been tapered to transform the mode area from 1700 μm2 to 900 μm2. We determine the exact length of the maximum pulse compression and numerically demonstrate the compression of a 250 fs, 100 kW peak power input pulse to 15 fs, 850 kW at 1.55 μm wavelength and compression of 250 fs, 120 kW peak power input pulses to 28 fs, 700 kW and to 46 fs, 500 kW at 1.8 μm and 2 μm wavelengths, respectively. Such a fiber can find wide ranging applications, including in communication, spectroscopy and medicine.

摘要： Bend performance of a single trench large mode area fiber with a step-index core is investigated. The introduced step-index core distribution of the fundamental mode. Numerical results demonstrate the designed fiber can achieve a high loss ratio (as high as 886) at the wavelength of 2 μm when the bend radius is only 10 cm.

摘要： Generation of high-peak-power, femtosecond pulse train and pulse doublet has been numerically demonstrated by exponentially decreasing the dispersion along the length of the large-mode-area segmented-cladding fiber. Such pulse trains find applications in various nonlinear optical processes.
