Mode-locked oscillators in the positive and negative dispersion regimes: scenarios of destabilization
Vladimir L. Kalashnikov, Evgeni Sorokin
We analyze the influence of spectrally modulated dispersion and loss on the stability of mode-locked oscillators. In the negative dispersion regime, a soliton oscillator can be sta…
Development prospects and stability limits of the mid-IR Kerr-lens mode-locked lasers
V. L. Kalashnikov, E. Sorokin, I. T. Sorokina
The Kerr-lens mode locking ability and the ultrashort pulse characteristics are analyzed numerically for the Cr-doped ZnTe, ZnSe, ZnS active media. The advantages of these material…
Spectral Characteristics of Ultrashort Pulses in Kerr-lens Mode-Locked Lasers
V. L. Kalashnikov, E. Sorokin, I. T. Sorokina
A number of factors that influence spectral position of the femtosecond pulse in a Kerr-lens modelocked Cr:LiSGaF laser have been identified: high-order dispersion, gain saturation…
