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.

Method and system for producing light of specified wavelength

The olive oil-tuned broadband conjugated polymer laser medium includes the conjugated polymer known as poly ((9,9-dihexyl-9H-fluorene-2,7-vinylene)-co-(1-methoxy-4-(2-ethylhexyloxy)-2,5-phenylenevinylene)) or 'Poly(FV-co-MEHPV)' at a 90:10 mole ratio. The emission wavelength of the olive oil tuned broadband conjugated polymer laser can be reversibly tuned between 500 nm and 680 nm.
