Employing Jones theory, thermal self-induced depolarization in high power conventional Faraday isolators is investigated with single mode and multimode lasers. The results show that depolarization in high power isolators is composed of depolarization induced by linear birefringence and depolarization induced by circular birefringence, and both are proportional to square of laser power; with a constant laser power, depolarization induced by linear birefringence is beam radius independent, but depolarization induced by circular birefringence increases with decrease of beam radius. Both depolarizations are reduced by multimode incidence. Depolarization induced by linear birefringence with multimode incidence is only 0.6 times that with single mode. Reduction of depolarization induced by circu
