Ảnh hưởng của tham số mất mát phụ thuộc thời gian lên hoạt động của laser ngẫu nhiên hai mode

In this paper, we investigated the influence of time-dependent losing coefficient

on the characteristics of the laser mode by solving the rate equations system which

describe the variation in photon density of two-mode random laser. The results showed

that when the losing coefficient depends on the time of the characteristics of the modes

such as the photon density, the time to reach the maximum value of the photon density

and the pulse duration of the emitting mode were changed. The received results give us

more knowledge about the influence of time-dependent losses on the operation of the

two-mode random laser.
