Abstract
The paper presents the measurement results of optical amplifying characteristics of Er-doped As-S-Ge chalcogenide glasses. The measurements included the amplification of useful laser source power during propagation along two axes of samples. A fluorescence maximum at the wavelengths between 1500 nm and 1540 nm was identified, which corresponds to the transition of electrons from the 4I13/2 level to the 4I15/2 level within the 4f shell of Erbium ions (Er3+). Measuring the signal strength showed that the passage through the erbium doped chalcogenid glass amplification of the useful signal occurs and this increase is proportional to the length of propagation through the doped glass.

Rezultati merenja zavisnosti snage laserskog signala prilikom prolaska kroz uzorak od talasne dužine svetlosti, pokazuju da je najveća vrednost izlaznog signala u intervalu talasnih dužina od 1526 do 1534 nm
Merenje snage laserskog signala koji je prolazio kroz halkogenidno staklo [(As2S3)30 (GeS2)70]1-y(Er2S3)y dopirano sa 0,5 at% Er, koje je istovremeno bilo pobuđivano ksenonskom lampom, pokazalo je da dolazi do pojačanja snage signala
Summary
Prodor u ove oblasti talasnih dužina je od velikog značaja u optoelektronici i smatra se da će halkogenidna stakla dopirana retkim zemljama preuzeti vodeću ulogu optičkih pojačavača, kao što je u doba razvoja elektronike imao tranzistor [1]. Snaga laserske svetlosti koja je prošla kroz uzorak izmerena je meračem snage PM300 na koji je montiran optički senzor S122B [9], slika 2. Izvor laserske svetlosti je Agilent 81949A koji emituje svetlost u intervalu talasnih dužina od 1518 do 1630 nm, dok se snaga može menjati u intervalu od 5 do 30 mW [10].
