We demonstrated an optimization of a picosecond fiber amplifier based on Yb-doped tapered fiber in a spectral range of 1030 nm. Nonlinear effects limiting peak power scaling (stimulated Raman scattering and four-wave mixing) were studied and factors

The possibility to scale-up output pulse energy in diffraction-limited Er-doped fiber amplifier has been studied. It is shown that the utilization of tapered fiber design allows one to increase the pulse energy up to 2 mJ, while keeping the diffracti

A tapered Er-doped fiber amplifier for high peak power pulses amplification has been developed and tested. The core diameter changed from 15.8 µm (mode field diameter (MFD) 14.5 µm) to 93 µm (MFD 40 µm) along 3.7 m maintaining single-mode perform

There is a high demand for fiber-based sources of high-peak and high-energy pulses in many fields, e.g. micro machining. A classical approach to generate such pulses is the chirped pulse amplification (CPA) method, where pulses consequently propagate

Ultra-highly-Yb-doped silica-based fibers are of great interest for such application as high-repetition rate mode-lock lasers (for reduction of the cavity length) and single frequency lasers (for increase pump absorption in a short, few cm in length,
