Problems solved by technology

Although laser excitation of electrospun polymer micro-nanofibers has been demonstrated via Fabry-Perot cavity or random cavity effect, the lasing threshold is relatively high, and the resonant excitation mode is difficult to be tuned to single-mode lasing.

Abstract

The invention provides a method for preparing a stretchable single mode laser element. The stretchable single mode laser element is prepared by using electrostatic spinning technology. The single modelaser element comprises a polymer micro-nano fiber with a diameter ranging from 0.5-4 micrometers; a polydimethylsiloxane (PDMS) substrate which is in a cuboid shape with a groove; an optical micro-bottle cavity, wherein the optical micro-bottle cavity is hung on the polymer micro-nano fiber, the diameter of the short shaft is 3-8 micrometers, and the component of the optical micro-cavity is a resin solution doped with a laser dye. The using method comprises the following steps: the stretchable single-mode laser element can realize efficient single-mode laser output in the micro-cavity of thepolymer bottle by adjusting the interference spot of the excitation light; by stretching the substrate, the adjustability of the peak of the excitation spectrum is realized.

Description

Technical field[0001]The invention relates to a micro-nano optical device, in particular to a method for preparing a stretchable single-mode laser element by electrostatic spinning.Background technique[0002]In the past two decades, whispering gallery mode (WGM) microresonators have attracted extensive research attention due to their low laser threshold and high quality (Q) factor. The direction of methodology and material production are the two basic elements for manufacturing new microresonators, which lay the foundation for the wide application of microresonators in various fields.[0003]In the past few years, different WGM geometries (such as discs, spheres, rings, cylinders, and polygons) and various materials (such as silicon dioxide, semiconductors, and polymers) have been extensively studied. Currently, WGM microresonators are designed such as melting, photolithography, thermal evaporation, direct stretching, femtosecond laser writing and surface tension induced self-assembly ...
