Evaporation characteristics of Er${}^{3+}$ doped silica fiber and its application in the preparation of whispering gallery mode lasers

Angzhen Li, Jonathan M. Ward, Ke Tian +6

The fabrication of whispering gallery lasers (WGL) is used to experimentally evaluate the evaporation rate (mol/$\mu$m) and ratio (mol/mol) of erbium and silica lost from a doped fib…
