Vedclass · Answer

(C) In a ruby laser,the active medium is a ruby crystal ($Al_2O_3$ doped with $Cr^{3+}$ ions).When the ruby crystal is pumped with high-intensity light,the $Cr^{3+}$ ions are excited to higher energy levels.These ions quickly decay to a metastable state,which has a relatively long lifetime.Stimulated emission occurs when these ions transition from the metastable state to the ground state,releasing photons of a specific wavelength $(694.3 \ nm)$.Therefore,the stimulated emission in a ruby laser is due to the transition from the metastable state to the ground state.

In ruby laser,the stimulated emission is due to transition from
