摘要:
We demonstrate the broadband stimulated emission generation in the Er3+/Tm3+/Ho3+ codoped optical fiber rod (ETHOFR). The absorption spectra, broadband emission, energy level, electron transition process, and optical stimulated emission of this codoped material are analyzed. Broadband spectrum amplification from 1.7 to 2.1 mu m is observed when ETHOFR is excited by 793-nm laser diode (LD). The optical gain shows similar wavelength in dependence on luminescence properties. This material holds potential in the application of weak optical signal amplification.
