Abstract

The results of a theoretical study of pump absorption properties in the colinear side-pumping schemes with pumping loops and absorption loops are presented. For side-pumping schemes with pumping loops, the number of pumping loops affects the pump absorption obviously: the more pumping loops, the higher pump absorption; and the pump light is absorbed effectively after propagating through all the loops. For side-pumping schemes with absorption loops, more loops results in a larger doped region, which leads to higher pump absorption efficiency.
