Optical inversion
WebPopulation inversion is a state of a system, for example a laser gain medium, where a higher-lying energy level is more strongly populated than a lower-lying level. This cannot occur under conditions of thermal equilibrium, where the level populations are described by a Boltzmann distribution. However, a population inversion is often easily ... There are three types of possible interactions between a system of atoms and light that are of interest: If light (photons) of frequency ν12 passes through the group of atoms, there is a possibility of the light being absorbed by electrons which are in the ground state, which will cause them to be excited to the higher energy state. The rate of abs…

WebThe exact nature of these mechanisms remains poorly understood, but the process of perception seems to involve at least two inversions: one (optical) inversion of the image … Almost any laser active gain medium can be pumped to produce gain for light at the wavelength of a laser made with the same material as its gain medium. Such amplifiers are commonly used to produce high power laser systems. Special types such as regenerative amplifiers and chirped-pulse amplifiers are used to amplify ultrashort pulses.

The lens apparatus would be a bit heavy to use as an inversion mechanism, but the prisms (Porro prims for instance) could do the job. They can provide a decent field of view.
