Abstract

The disclosed micro-fiber circular-junction dye laser with swift-away wave coupled gain comprises: using a first micro-fiber to prepare circular-junction resonant cavity with two ends connected with a mono-mode fiber and second micro-fiber respectively; dipping the resonant cavity into a solution doped gain medium to generate laser and output from the second micro-fiber. This invention is small-size, stable and convenient to be integrated.

Description

technical field [0001] The invention relates to micro-optical elements, in particular to a micro-fiber ring-junction dye laser utilizing evanescent wave coupling gain. Background technique [0002] Microlaser is an important optoelectronic device, which has broad application prospects in optical information processing, as well as biological and chemical sensing. With the improvement of the optical fiber preparation process, low-loss micro-nano fibers have been prepared and have been applied to the production of micro-nano photonics devices. Micro-fiber ring junction resonators and rare earth-doped micro-fiber ring junction lasers have been proven. The miniature lasers that utilize evanescent wave coupling gain that have been realized in the world mainly include spherical and cylindrical structures. However, these structures are not stable enough for optical integration and difficult to be applied in practice. Contents of the invention [0003] The object of the present i...
