A method for producing light of a specified wavelength includes irradiating a dye solution present in a cuvette with a semiconductor diode laser source to emit laser light. A system for producing a light of a specified wavelength includes a semiconductor diode laser source, an optical chopper, a cylindrical lens, a dye preparation unit, a grating, and a dye solution pump. The dye preparation unit includes a rotator and a cuvette loaded with a dye solution, which includes a dye solution. The dye solution comprises a natural oil selected from moringa, avocado, almond, castor, pumpkin, lemon oils, or combinations thereof, with dissolved dye at concentrations of 1-3 μg/mL. This configuration enables enhanced amplified spontaneous emission intensity at elevated temperatures while maintaining photochemical stability.
