Just need help finding the refractive index as a function of pressure and temperature. Specifically part B of the problem.

I1Just need help finding the refractive index as a function of pressure

82.2. A C02 laser is composed of 80% N2, 19% He and 1% CO; at a total pressune of 20 Ton at room temperature. The index of refraction at 10 pm of N3 is 1.00029, He is 1.00003 and CO; is 1.00042 at NTP (1 atm and T = 293K). a) Find the index of reection for this laser nuxture. b) The laser mode positions of the resonant cavityr containing this gain medium will be shifted as the pressure of the gain medium changes. Find where p is the total pressure of the gain medium and T is the temperature. :3) Considering CO; lasers have been constructed with a stable 100 Hz bandwidth, is pressure variation of the index of refraction a sigiieant concern for owing. gas lasers
