A TEA laser is a gas laser energized by a high voltage electrical discharge in a gas mixture generally at or above atmospheric pressure. The most common types are CO2 lasers and Excimer lasers, both used extensively in industry and research. The acronym "TEA" stands for Transversely Excited Atmospheric.
