Problems solved by technology

In addition, the difficult-to-manipulate substrate material not only affects the laser emission intensity, but also makes it difficult to couple due to its large size, which limits the development and application of random laser devices to a certain extent.

Embodiment

[0020] The main structure of the inkjet printing system described in this embodiment includes a needle tube, needle tip, printing ink, high voltage, PDMS flexible substrate, electrode plate and precision control mobile platform. The needle tip is installed under the needle tube and connected to the needle tube, and the needle tube realizes the z direction ( vertical direction) to control the distance between the needle tip and the PDMS flexible substrate to realize the jetting out of the printing ink; the PDMS flexible substrate is placed above the electrode plate, and the micro-nano Level movement, so as to obtain different shapes of printed structures; apply a high voltage (generally hundreds of volts to thousands of volts) between the needle tip and the electrode plate, and the printing ink will be ejected from the needle tip through the action of the electric field force, and adhere to the The PDMS flexible substrate surface; the movement of the needle tube and the precisio...

Abstract

The invention belongs to the technical field of lasers, and relates to a method for producing grapheme enhancing flexible dye random laser through ink jet printing. The method comprises the steps thatprinting ink is firstly put into a printing needle tube, the printing ink flows into a needle tip freely, a flexible substrate is fixed to an electrode board, high voltage is exerted between the needle tip and the electrode board, the needle tube is moved freely in the vertical direction, the moving of the flexible substrate is controlled through the program of an externally connected computer, the flexible substrate is moved according to the preset program of the computer to achieve the printing of different shape structures, standing is allowed for an obtained sample after printing is completed for the obtained sample to condense, and therefore the grapheme enhancing flexible dye random laser is obtained. The method has the advantages that the designing is simple and visual, the methodis flexible and convenient, the principal is reliable, the achievement is easy, a flexible material PDMS is taken as a substrate to improve the bending and folding performance of the random laser, thecoupling with other photonic device is easier, and the quantitative control on the property of random laser can be achieved by the mechanical parameter adjustment of the substrate.

Description

Technical field: [0001] The invention belongs to the technical field of lasers, and relates to a process for making graphene-enhanced random lasers, in particular to a method for making random laser systems by inkjet printing. Background technique: [0002] Random laser (Random Laser) is a laser generated by nonlinear enhancement of stimulated emission in a disordered scattering system through multiple scattering. Unlike conventional lasers, which require finely tuned resonators, stochastic lasers do not require a conventional laser cavity, but instead rely on the localization of photons. People have realized the generation and regulation of random lasers based on semiconductor nanostructures, polymer films, quantum dots, biological tissues, photonic crystals, etc. Random lasers have the characteristics of small size, high quality, and cavity-free emission, and have great potential in optical integration. application potential. Random lasers provide a feedback mechanism by...
