3 cards from this section. Quick, good the night before a test.
What is absorption in the context of laser physics?
Think about what happens to an atom when it takes in energy.
Define spontaneous emission.
Consider what happens naturally when an atom is excited.
What is the main mechanism by which lasers operate?
Think about which process involves the emission of identical photons.
True or False: Population inversion occurs naturally and does not require additional energy.
Consider how energy dynamics work in atoms.
Calculate the wavelength of light emitted when an atom transitions from a higher energy level of 3 eV to a lower level of 1 eV.
Apply the energy gap logically to the photon equation.
Examine how the properties of laser light make it suitable for fiber optic applications.
Consider the nature of how laser beams propagate.
