         In my Ph.D. thesis,  my research focused on the synthesis of new glass for laser application. I studied new prepared series of phosphate glasses doped Cr3+/Yb3+/Er3+ as a glass for laser application. This type of glass can be used for medical and military applications as the commercial glass Kigre. Indeed, the glasses these glasses showed high lifetimes for the emission level at 1530 nm greater than 8 ms and a quantum yield up to 87%.

Whereas the glasses codoped by Cr3 + / Yb3 + / Er3 + ions have important measured lifetimes that can reach 8.57 ms, thanks to energy transfer from Cr3 + ions to Er3 + ions, passing through the intermediate ion Yb3 +. Compared with commercial glasses, the measured lifetime of our glasses was much more interesting.
