The review of novel solid state lasers for coherent optical velocimetry is presented. The paper is focused on laser diodes as well as diode pumped lasers as the most prospective sources nowadays and in the future in this area of applications. The single frequency diode pumped lasers are discussed in detail. The novel concepts in velocimetry such as chirped lasers, two frequency lasers, and lasers with self-mixing effect are presented. The applications of solid state lasers to Doppler velocimetry, holographic methods in velocimetry, and coherent laser radars are discussed.
