How does a gas laser work
WebSimplified principle of Doppler laser cooling: 1. A stationary atom sees the laser neither red- nor blue-shifted and does not absorb the photon. 2. An atom moving away from the laser sees it red-shifted and does not absorb the photon. 3.1. An atom moving towards the laser sees it blue-shifted and absorbs the photon, slowing the atom. WebGas lasers In these lasers the lasing medium is made-up of one or a mixture of gases or vapors. Gas lasers can be classified in terms of the type of transitions that lead to their …
