Numerical analysis and experimental results of output performance for Nd-doped double-clad fiber lasers

Optimization of Yb3+-doped double-clad fiber lasers using a new approximate analytical solution

“…For most linear-cavity Yb 3 + -doped DCFLs, there are three types of pump configuration [16]: forward, backward and double-end pump configuration. All the types can be simplified to the system shown in Fig.…”

“…The forward-and backward-propagation beams in CW Yb 3 + -doped double-clad fiber lasers satisfy rate equations under steady-state conditions [16,17] …”

Modeling a CW Single-Frequency Yb:Silica Fiber MOPA System and Determination the Gain and Saturation in the Optimum Length

“…The calculations were running numerically in fourth order Raunge-Kutta method [5] and shooting technique was used for initial conditions [6]. The fiber is pumped by a fiber-coupled diode laser emitting 10 W at 930 nm.…”

Stimulated Brillouin Scattering (SBS) Suppression Techniques

“…Increasing the SBS threshold would therefore increase the transmission output potential. It has been shown that SBS threshold depends on several factors, including the spectral width of the pump wave, the length of the fiber, temperature, and fiber core diameter [1] [2][3][4][5][6].…”
