WebMost doped insulator solid-state lasers are well suitable for Q switching, since their gain media have long upper-state lifetimes and high saturation energies, and hence the capability to store large amounts of energy. The basis is that their laser transitions are weakly forbidden transitions with correspondingly low transition cross-sections . WebIf we divide this rate into the total energy of the state, we get a characteristic lifetime. It should come as a surprise to nobody that this is the same characteristic lifetime given by the Einstein A coefficient. The Einstein B coefficients, and of course the Q factors, are similarly calculable. climbing wall syracuse ny https://adoptiondiscussions.com
