The far-field emission of two-dimensional stadium-shaped microlasers is investigated. Stadium-shaped microcavities based on a laser dye embedded in a polymer matrix have been elaborated. Such stadium-shaped microresonators, made by lithography and reactive ion etching have displayed quality factors greater than 6000 and a high output power. The highly directional far-field pattern of the emitted beam (full width at half maximum ~15°) reflects the symmetries of the stadium shape.
