A Fabri-Perot interferometer is to be used to resolve the mode structure of a He-Ne laser operating at 632.8 nm. The frequency separation between the modes is 150 MHz. The plates are separated by an air gap and have a reflectance of 0.999. What is the coefficient of finesse of the instrument? What plate spacing is required? What is the free spectral range of the instrument under these conditions?
