Abstract
We demonstrate the broadband optical amplification in bismuth-doped strontium germanate glass with and laser diodes (LDs) as excitation sources. The net optical gain has been obtained within the wavelength region of 1272 to with laser diode under power. The maximum gain and gain coefficients are 1.23 and at , respectively. The signal increment at is 2.8 times with LD, under power. The differential thermal analysis measurement reveals the good thermal stability of the studied glass. This glass could be suggested as a promising gain medium for broadband optical amplifiers.
