TEA laser

[‚tē‚ē′ā ′lā·zər]
(optics)
A gas laser in which a glow discharge is maintained without arc formation at atmospheric pressure (which is relatively high for a gas laser) by using a discharge which is transverse rather than parallel to the optic axis. Derived from transversely excited atmospheric pressure laser.

Here we examine the performance of several of these sensor systems with a potential standoff threat detection capability in some detail, including an enhanced LIBS method, in which a collinear C[O.sub.2] TEA laser pulse is superimposed in time and space with the tripled or quadrupled output from an Nd: YAG laser as well as an enhanced Raman-based method known as stimulated Raman adiabatic passage or STIRAP [30].
The company provides Nd YAG laser drilling, cutting and welding, C[O.sub.2] laser cutting and welding, excimer laser drilling, micro-machining and ablation, and TEA laser and traces for medical, electronic or other technology applications.
The first, UltraOptec's laser ultrasonic inspection system (LUIS), developed by the Industrial Materials Institute (IMI) of the National Research Council Canada in Boucherville, Quebec, uses a carbon dioxide TEA laser to generate ultrasound in composites and an excimer laser for metals.
