LIGHT AMPLIFICATION by STIMULATED ELECTRON RADIATION. Question:. In movies, laser beams are always shown as bright pencils of light streaking through the air or space. If you were to look from the side at a beam from a powerful laser, would you be able to see that laser beam as it travels past you?. Einstein’s analysis:. Consider transitions between two molecular states with energies . E. 1. and . E. 2. (where . E. 1. < . E. 2. ). . E. ph. is an energy of either emission or absorption.. The tunable laser could be set to any desired wavelength either in the factory or in the field by a software command.. The performance parameters are:. Power. Spurious mode suppression.
