5 Questions
In a CO2 laser, energy transfer from N2 raises the CO2 molecules into an excited state, which then decays into one of several possible lower states by emitting a ______.
photon
Non-radiative losses cause the molecule to return to the ______ state.
ground
In a CO laser, several pumping mechanisms can raise the energy of the molecule to various excited states. It then cascades back down to the ______ state, emitting several photons along the way.
ground
CO lasers do not necessarily need ______.
nitrogen
Over 50 years ago, carbon monoxide (CO) lasers showed promise due to their efficiency in converting electrical energy into ______.
light
Learn about the energy transfer mechanisms in CO2 and CO lasers, including how excited states decay by emitting photons. Understand the differences between CO2 and CO lasers in terms of energy pumping mechanisms and nitrogen requirements.
