However, in the first living systems on earth, left or right-handed activity could have been adopted purely as a matter of chance and, once a particular asymmetry was established, it maintained itself. This conjecture implies that optic ...

Laser Molecular Spectroscopy CHE466 Fall 2007
... The efficiency of a laser is related to its ability to sustain a population inversion and regenerate a population in the low energy state to initiate a new pumping cycle. As you may see a 2 level laser would be very inefficient, because a population inversion may not be acquired as a result of popul ...
