Laser anemometers based on application of Doppler Effect have been developed and are used in-flight, on aircrafts for measurement of air flow parameters, mainly its speed versus the airplane. The air speed measurements are vital for safe flights. The main basic idea of Doppler techniques consists in measuring the frequency of scattered light. In this paper, we propose a study of a laser Doppler Anemometer using COMSOL Multiphysics®. The main purpose of this study is to provide essential data for an improved design of this type of laser devices. The use of Laser Doppler Anemometer COMSOL Multiphysics® simulations is under continuous development by using more and more realistic values of input constructive laser device parameters.
