Tapered laser diode
TOPTICA Photonics AG

Tapered amplifier (TA) diodes combine the "best of both worlds": Laser diodes designed for single mode operation as powerful as broad area emitters for highest output power. Usually, the power of a single mode diode is limited by Catastrophic Optical Mirror Damage (COMD) whilst the higher power of a broad area emitter has the drawback of multiple transverse mode operation. Using a special lateral geometry, where a single mode channel ensures operation at the fundamental transverse mode, while the power density on the output facet is greatly reduced by diffraction of the beam within a subsequent tapered gain section.
