Chia-Ming Liu;Chia-Ling Tsai;Yann-Horng Chen;Ping-Hsuan Yang;Chun-Nien Liu;Sheng-Lung Huang;Wood-Hi Cheng
The higher fluorescence intensity for a 300-nm broadband single-mode Cr-doped crystalline core fiber (SMCDCCF) are demonstrated with and without coating and thermal annealing, respectively. The 31% fluorescence improvement was mainly due to the Cr4+-concentration up to 1.2 times during coating and thermal annealing process.
