Multiphonon Absorption

Source: ResearchGate     Understanding Multiphonon Absorption in Optical Materials Introduction to Multiphonon Absorption In the realm of photonics, dielectric materials and semiconductors often exhibit a range of optical wavelengths where they are relatively transparent, meaning they have low absorption. This transparency range is bounded at the long-wavelength end by what is known as the […]

Multi-Phonon Transitions

Source: Nature Understanding Multi-Phonon Transitions in Laser Gain Media Understanding Multi-Phonon Transitions in Laser Gain Media In the realm of solid-state physics, particularly in laser technology, multi-phonon transitions play a crucial role. These transitions involve the simultaneous emission of multiple phonons, which are quanta of lattice vibrations, and are fundamental to the operation of various
