Paper Abstract

We proposed and investigated a novel tapered ytterbium-doped fiber design. The tapered fiber has length of 2.1 m, single-mode thin end and thick end with core/clad diameter of about 50/430 µm. Master-oscillator power-amplifier monolithic fiber scheme have been developed using this fiber and 5 ps duration, 28 nm spectral width and 0.5 MW peak power pulses was achieved at the output. FROG measurements reveal linear chirp that allow one to expect decompression of these pulses down to sub-100 fs duration.
