Laser-action
WebAlthough laser action is possible with only two energy levels, most lasers have four or more levels. Figure 4. Three level laser energy diagram. A Q-switch in the optical path is a method of providing laser pulses of an extremely short time duration. A rotating prism like the total reflector in figure 3 was an early method of providing Q-switching.

WebIf the shutter is closed, laser action cannot occur and the population inversion can be very high. If the shutter is opened suddenly, the stored energy will be released in a short and intense light pulse. This technique is known as Q-switching. Q here denotes the ratio of the energy stored to the energy dissipated in the cavity.

WebReturning to laser action, we must now modify the heavy curve of Figure 3.5 to take into account the f-factors. We know that if the Fermi level is in the conduction band then (f C - f V ) is a maximum at hv = U g and falls to zero when h v = U F C − U F V .
