Since some week I read all i can about laser (Web, books) and i am very =
surprise that there is very few kind of laser (I visible or near =
spetrum). (Ar, Kr, Ne, Cd, Cr, Cu, Au, CO2, N2, Rare Earth and =
Semiconductors)
Is it a physical limitation ?
Is there some predictive calculation to know if one other element ( like =
Fe, Zn ...) is able to be use as a laser medium ?
I look in atomic transition probability tables, but for instance i don't =
find a maner to explain why Ar+ Kr+ or Cu++ lase.
Is there some one who heard about this kind of research.
What atom properties explain the stmulated emission and for some the =
superradiance emission.
