Simple rate-equation model for two-photon lasers.
We present a rate-equation model for two-photon lasers that, despite its simplicity, captures the essential physics of their behavior and affords an intuitive understanding of their novel threshold and stability behavior. We use the model to investigate the steady-state behavior of the laser, explore the stability of the steady-state solutions, and predict the injected pulse strength needed to ...
متن کاملRate-equation model for multi-mode semiconductor lasers with spatial hole burning.
We present a set of rate equations for the modal amplitudes and carrier-inversion moments that describe the deterministic multi-mode dynamics of a semiconductor laser due to spatial hole burning. Mutual interactions among the lasing modes, induced by high- frequency modulations of the carrier distribution, are included by carrier-inversion moments for which rate equations are given as well. We ...

nowadays in trade and economic issues, prediction is proposed as the most important branch of science. existence of effective variables, caused various sectors of the economic and business executives to prefer having mechanisms which can be used in their decisions. in recent years, several advances have led to various challenges in the science of forecasting. economical managers in various fi...
Low-threshold two-photon pumped ZnO nanowire lasers.
We report in this communication the two-photon absorption (TPA)-induced room-temperature lasing performance of ZnO nanowires. Under femtosecond pulse-excitation at lambda = 700 nm in the infrared regime, a remarkably low threshold of 160 microJ/cm(2) was observed for the TPA-induced lasing action, which is of the same order of magnitude as that measured for the linear lasing process. Time-resol...
متن کاملThe time development of adiabatic two - photon absorption : 11 . Rate equation regime
The time dependence of the two-photon absorption process is experimentally investigated in the intermediate intensity rate equation regime, where incoherent relaxation plays an important role, as a function of laser linewidth and Doppler width. The saturation effects observed are in excellent agreement with the predictions of Allen and Stroud.
