Abstract
The present invention relates to a random lasing photo-curable composition (1) for use as random lasing gain medium comprising:—laser dye molecules (11);—an optical glue (12) for the laser dye molecules to be suspended therein; wherein the optical glue is mercapto ester-based and comprises methacrylate and/or derivatives thereof. The present invention also relates to a random lasing system with a gain medium made of at least partially of random lasing photo-curable composition, and methods for manufacturing such random lasing system.
Claims18
A random lasing photo-curable composition for use as random lasing gain medium comprising:
- laser dye molecules;
- an optical glue for the laser dye molecules to be solvated therein;
- wherein the optical glue is mercapto ester-based and enables random lasing when in the composition, and wherein the optical glue solvates the laser dye molecules.
A method for manufacturing a gain medium in a solid form for a random lasing system, the method comprising:
- mixing laser dye with an optical glue to obtain a photo-curable mixture;
- coating a substrate with the photo-curable mixture;
- masking the substrate with a pattern-baring mask;
- irradiating the substrate through the mask;
- removing the mask;
- washing uncured photo-curable mixture;
- wherein the optical glue is mercapto ester-based and enables random lasing when in the composition, and wherein the optical glue solvates the laser dye molecules.
A method for manufacturing a gain medium a liquid form contained in a cell for a random lasing system, the method comprising:
- mixing laser dye with an optical glue to obtain a photo-curable mixture;
- filling the cell with the photo-curable mixture;
- closing the cell;
- wherein the optical glue is mercapto ester-based and comprises methacrylate and/or derivatives thereof.
