На основе численного решения уравнений Максвелла–Блоха исследовано взаимодействие коротких импульсов света с резонансными усиливающими средами. Рассмотрены импульсы различной формы – с огибающими гауссова, прямоугольного и экспоненциального вида, последний из которых привлекает повышенное внимание благодаря возможности реализации с его помощью таких новых эффектов, как виртуальное поглощение. Показано, что выбор формы и длительности падающих импульсов позволяет управлять интенсивностью и временем генерации усиленного излучения, а также динамикой населенностей уровней среды.

Using the numerical solution of the Maxwell–Bloch equations, we study the interaction of short light pulses with resonant amplifying media. We consider pulses of various shapes – with Gaussian, rectangular, and exponential envelopes, the latter of which has recently attracted increased attention due to its potential for implementing new effects such as virtual absorption. We show that by choosing the shape and duration of the incident pulses, we can control the intensity and time of the amplified radiation generation, as well as the population dynamics of the medium levels.
