In-depth study of spectroscopic properties of new $P{r}^{3+}$-ion doped low-phonon sesquisulfide $L{u}_2{S}_3$ material for mid-IR laser sources

Martin Fibrich, Jan Sulc, Lubomír Havlak +6

$L{u}_2{S}_3$ material from the family of sesquisulfide hosts appears to be a promising low-phonon material for use as a laser gain medium allowing for a laser emission over a broad sp…
