Consider the round-trip gain expression G = R1 R2e2(g–a)l a. For a laser constructed with medium that has a gain of 0.03/cm but absorption a of 0.01/cm, if the mirrors are both of reflectivity R1 = R2 = 0.99, what gain length is necessary to get positive roundtrip gain/get it to lase (G > 1)? b. For a laser medium 20 cm in length, with negligible absorption a, if the gain g of the medium is 0.01/cm, the high-reflective mirror has reflectivity Rz = 0.999, what is the minimum reflectivity R2 that the second mirror needs to have if order to have positive round-trip gain G?
