Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

In this paper the dynamics of a two-mode semiconductor laser model is considered. The dynamic evolution of a two -mode semiconductor laser can be described by nonlinear rate equations, which take in account the gain saturation. Changes in parameters of the system can lead to changes of the character of the solutions. Qualitative analysis of the system is used for investigating the typical bifurcations and allowed conditions for the existence of different types of mode oscillations in the system. The phase portraits of steady state solution of system are plotted using numerical methods. The competition phenomenon between modes is observed.
