On new formulas for line form and natural linewidth in semiconductor lasers

Simulation of natural linewidth and line form for semiconductor lasers; Interpretation of experiments

“…A formula for the line form varying from (5) in that , was proposed in [17]. But the calculations done in this paper have shown that , defining amplitude fluctuations, makes the basic contribution to the natural linewidth.…”

“… was proposed in[17].But the calculations made in this paper have shown that A B , defining amplitude fluctuations, makes a basic contribution to the natural linewidth. Hence it is impossi-.…”

“…The strict approach demands definition on line form and natural linewidth based on statistics. In this paper, formula (3) will be used for deriving the line form and natural linewidth of the mode, basing on T АПЭП -2012 ♦ ХI МЕЖДУНАРОДНАЯ КОНФЕРЕНЦИЯ 38 the representations about creating a laser line form as a result of superposition of spontaneous radiation on laser radiation studied by a special method of the spectral theory of stochastic processes [17] which is developed in this paper (detailed calculation of the formula for line form for radiation inside laser is presented in APPENDIX A). The formula for line form for radiation inside laser is derived in the form (see (A.4) and (A.5)):…”

On the line form and natural linewidth; Simulation and interpretation of experiments

“…A formula for laser form, differing from (2) in that 0 A B = , was proposed in [11]. But the calculations made in the paper have shown that A B defining the peak fluctuations influences the natural linewidth.…”

“…The formula (1) will be used for deriving the line form and natural linewidth of the mode, basing on the representations of t creating a laser line form as a result of superposition of spontaneous radiation on laser radiation studied by a special method of the spectral theory of stochastic processes [11] which is developed in the present paper. In our paper, the formula for the line form for radiation inside the laser is derived as…”
