Example: A certain laser cavity of type shown in figure 5-6 has a mirror separation of 30 cm. The He-Ne laser gain medium is capable of supporting laser light of wavelengths in the range from l1 = 632.800 nm to l2 = 632.802 nm. Find: • The approximate number of half-wavelengths that fit into the cavity. • The range of frequencies supported by the He-Ne gain medium. • The difference in the frequencies of adjacent standing wave nodes of the cavity. • The number of standing wave nodes that will likely be present in the laser output.
