Based on the obtained characteristic equation and its roots, the dynamical behavior of the system and the threshold of the instability are analyzed. For the stable operation of the system and with the use of the time series curves, it is possible to study the dynamical behavior and the stability ranges of the laser in the presence of the saturable absorber and the gain environment. This paper aims to achieve from quasi-periodic behavior in a solitary laser to the generation of a pulse train from two mutually coupled lasers in the presence of saturable absorbers. Also, the stability range for a solitary laser and then for two coupled lasers in the presence of saturable absorbers have been studied.</span></span></span><br> <br> &nbsp; Hybrid mode locking, Numerical analysis, Pulse generation, Stability analysis, Semiconductor laser, Saturable absorber. 81 92 http://ijop.ir/browse.php?a_code=A-10-953-1&slc_lang=en&sid=1 Erfan Abbaszadeh Jabal Kandi erfanabbaszadeh38@gmail.com 10031947532846004958 10031947532846004958 No Department of Physics, Faculty of Science, Urmia University, Urmia, Iran Khosro Mabhouti kh.mabhouti@urmia.ac.ir 10031947532846004959 10031947532846004959 Yes Department of Physics, Faculty of Science, Urmia University, Urmia, Iran Rahim Naderali r.naderali@urmia.ac.ir 10031947532846004960 10031947532846004960 No Department of Physics, Faculty of Science, Urmia University, Urmia, Iran Neda Samadzadeh samadzadehneda@gmail.com 10031947532846004961 10031947532846004961 No Department of Physics, Faculty of Science, Urmia University, Urmia, Iran
