Er-doped Ortho- and Metha-phosphate Glassy Mixtures for 1.54 ?m Laser Construction

Popis výsledku v původním jazyce

The goal of our work was preparation and investigation of Er-doped potassium ytterbium lanthanum ortho-and metha-phosphate glassy mixtures developed as a solid-state laser active medium. The tested samples were prepared by rapid quenching of molten mixture of starting K2CO3 , YbPO4 , LaPO4 , YbPO4 and P2O 5 . Their cations molar concentration was as follows n(K) = 0.7, n(Yb) = 0.135, n(La) = 0.16 and n(Er) = 0.005 and it was the same in all tested samples. The additions of the P2O5 to the individual starting charges were batched so the following compositions of resulting glasses should be obtained: (i) pure meta-phosphate, (ii) mixture of 80 mol% of meta-phosphate and 20 mol% of ortho-phosphate, (iii) mixture of 50 mol% of meta-phosphate and 50 mol% ofortho-phosphate, (iv) mixture of 25 mol% of meta-phosphate and 75 mol% of ortho-phosphate, and (v) pure ortho-phosphate. The glassy samples were prepared in the form of discs about 8mm in diameter and 2mm in height. The absorption spectr
