Custom optical glasses

Custom optical glasses

Description

We design, fabricate and characterize optical glasses for lasers and amplifiers in the Near-IR and for nonlinear applications in the Mid-IR. Glass families include: tellurite, phosphate, germanate, silicate.

A) Rare-earth doped phosphate and undoped tellurite and germanate glasses

We synthesize custom Er, Yb, Er/Yb and Nd-doped phosphate glasses to be used as active media for compact lasers and amplifiers operating in the Near-IR region. We also develop passive germanate and tellurite glasses for supercontinuum generation in the Mid-IR.

Keywords

Phosphate glasses, tellurite glasses, germanate glasses, silicate glasses, rare-earth ions.
