Nonlinear mirror modelocking of a bounce geometry laser

Nonlinear Vibration Analysis of a cantilever beam with nonlinear geometry

Analyzing the nonlinear vibration of beams is one of the important issues in structural engineering. According to this, an impressive analytical method which is called Modified Iteration Perturbation Method (MIPM) is used to obtain the behavior and frequency of a cantilever beam with geometric nonlinear. This new method is combined by the Mickens and Iteration methods. Moreover, this method don...

Asymptotic states of the bounce geometry

We consider the question of asymptotic observables in cosmology. We assume that string theory contains a landscape of vacua, and that metastable de Sitter regions can decay to zero cosmological constant by bubble nucleation. The asymptotic properties of the corresponding bounce solution should be incorporated in a nonperturbative quantum theory of cosmology. A recent proposal for such a framewo...

Laser modelocking and dual wavelength lasing in silicon

Nonlinear optics in silicon has drawn substantial attention in the recent years. In this research, laser mode-locking and dual wavelength lasing are achieved in a fiber-ring-cavity using an Erbium–doped fiber amplifier (EDFA) as a gain medium and a 1.7cm long silicon-on-insular waveguide as pulse compressor, a mode-locker and a Raman gain media. We show that the transient behavior of two photon...
