激光在湍流大气中传输，光斑尺度、偏移角度及光强起伏均与传输距离和湍流强度的关系-Laser transfer in turbulent atmosphere, spot scale, offset angle and light intensity fluctuations are related to transmission distance and the turbulence intensity of the relationship between the

EDFA matlab coden Erbium Doped Fiber Amplifier (EDFA) consists of a piece of fiber of length L, whose core is uniformly doped with Erbium ions. Such ions can be thought of as simple two-level systems, i.e., they can have only two energy states: 1) a
