PbSe quantum-dot-doped phosphate glasses as material for saturable absorbers for 1-3 μm spectral region

摘要

Narrowly size distributed PbSe quantum dots were fabricated in phosphate glasses doped with PbO+ZnSe and PbSe by thermal treatment. Absorption spectra in 3 μm range are studied for the first time. Non-linear absorption of the samples near 1.54 μm is studied.
