4 cards from this section. Quick, good the night before a test.
What is stimulated emission?
Think about how lasers amplify light.
Define population inversion.
Contrast it with a normal energy distribution.
What is the primary mechanism that allows lasers to emit coherent light?
Think about what triggers the emission of light in lasers.
True or False: Population inversion means that more atoms are in the ground state than in the excited state.
Recall the definition of population inversion.
Describe how a CO₂ laser is capable of cutting through metal, focusing on the interaction between the laser and the material.
Think of heat generation and material properties.
Given a laser with a wavelength of 532 nm, calculate the energy of each photon generated. Use the formula E = hc/λ.
Make sure to convert all measurements to SI units.
