These lasers utilize excited states of molecules, which can involve electronic excitation as well as vibrations and rotations of the molecules. As a result, molecular gas lasers
Source: Wikipedia Understanding Optical Activity Optical Activity Overview Optical activity refers to the ability of certain substances to rotate the polarization direction of light passing through them. This phenomenon includes optical rotation and circular dichroism, which are key characteristics of optically active materials. Causes of Optical Activity Optical rotation occurs in substances with asymmetric molecular
