Transcribed Image Text:Problem 63.
64 Martian CO, laser. Where
sunlight shines on the atmosphere
E = 0.289 eV
of Mars, carbon dioxide mole-
cules at an altitude of about 75
km undergo natural laser action.
The energy levels involved in the
action are shown in Fig. 40-26;
population inversion occurs be-
tween energy levels E, and E.
(a) What wavelength of sunlight
E = 0.165 ev
E =0
excites the molecules in the las-
Figure 40-26 Problem 64.
ing action? (b) At what wave-
length does lasing occur? (c) In what region of the electromag-
netic spectrum do the excitation and lasing wavelengths lie?
