| Abstract [eng] |
In this work was investigated ultrashort pulse Yb-doped ring fiber generator based on self-phase modulation and alternating spectral filtering. Influence of pump power and filter spectral band separation parameters on the pulse generation and on the received pulse parameters were investigated. It was found that that pulses can't be generated without external pulse source. Maximum average power decreases with increasing fiber generator‘s spectral separation of filter bands when pump power is fixed. It was discovered that with increasing filter spectral band separation, the generated pulse spectra becomes wider and the duration of pulses increases with increasing pump power. Also the duration of the compressed pulses was decreasing with increasing pump power. |
