摘要	It is an object of the invention to provide a VCSEL having both a high beam quality or a low M 2 -factor, respectively, and a reduced mirror thickness which improves the heat dissipation due to the reduced thickness and the production cost. It is suggested to employ a Bragg-reflector in combination with a metal reflector terminating the distal side of the Bragg-reflector as seen from the laser cavity,wherein the metal reflector layer is localised at the centre around the optical axis.
其他摘要	本发明的一个目的是提供一种VCSEL，其分别具有高光束质量或低M 2因子，以及减小的镜子厚度，由于减小的厚度和生产成本而改善了散热。建议采用布拉格反射器结合金属反射器，该金属反射器终止从激光腔看到的布拉格反射器的远侧，其中金属反射器层位于围绕光轴的中心。
主权项	A vertical cavity surface emitting laser diode (1), comprising - a substrate (2) and disposed thereon, -a first Bragg-reflector layer stack (5), -a second Bragg-reflector layer stack (9), said first and second Bragg-reflector layer stacks (5, 9) forming a laser cavity with an optical axis (3) along which a laser beam is emitted in operation; -a metallic reflector layer (15) terminating one of the Bragg-reflector layer stacks (5, 9), said metallic reflector layer (15) being localised about said optical axis (15) and covering an area no larger than an area within which the intensity of the TEMoo- laser mode exceeds more than one third of its maximum intensity.
