Abstract

The frequency upconversion of a 1313nm Nd:YLF laser pulse to 780nm through the amplified spontaneous emission (ASE) in the Er³⁺-doped and Er³⁺/Yb³⁺-doped GeO₂/SiO₂ single-mode optical fibers pumped by a CW mode-locked (CW+ML) laser or a Q-switched mode-locked (QS+ML) laser was observed respectively. It was found that the emission at 780nm corresponds to ⁴I_9/2 -⁴I_15/2 transition, and its pumping mechanism is accomplished by a first step resonant two-photon absorption to ⁴F_9/2 state, followed by a fast nonradiative relaxation to ⁴I_9/2 state. The conversion efficiency pumped by the CW+ML laser is higher than the one pumped by the QS QS+ML laser with the peak laser power being several hundred times higher.
