Catalog: Tapered Lasers And Amplifiers

Tapered diode lasers combine a nearly diffraction limited beam quality with output powers which have previously only been available for diode lasers with broad-area design. To achieve these characteristics, the lateral design consists of a taper and a ridge-waveguide section. High beam quality is made possible via an index-guided ridge-waveguide or MESA structure. In contrast, high output power requires a gain-guided broad pumped area which leads to a taper section.
