Method and system for producing light of specified wavelength

A system for producing a light of a specified wavelength, comprising:

• a semiconductor diode laser source,
• an optical chopper,
• a cylindrical lens,
• a dye preparation unit,
• a grating, and
• a dye solution pump;
• wherein the semiconductor diode laser source is configured to emit and direct laser light toward the optical chopper;
• wherein the optical chopper is configured to modulate the laser light by pulsing the light at intervals and to direct the laser light toward the cylindrical lens;
• wherein the cylindrical lens is configured to shape the laser light and direct the laser light toward the dye preparation unit;
• wherein the dye preparation unit comprises:
• a cuvette, loaded with a dye solution, which comprises a dye dissolved in an oil selected from the group consisting of moringa, avocado, almond, castor, pumpkin, lemon, and combinations thereof;
• a rotator, wherein the rotator is configured to rotate the cuvette;
• and
• an active temperature control apparatus configured to monitor and maintain a stable temperature within the cuvette utilizing active heating and cooling;
• wherein the dye preparation unit is configured such that the laser light passes through the dye solution and excites the dye, thereby emitting dye-emitted light and the laser light and the dye-emitted light combine to produce an enriched laser light;
• wherein the grating is configured to selectively transmit a desired wavelength of light to produce an output light, and direct the output light toward a target;
• and
• wherein the dye solution pump is configured to pump dye solution from a dye solution reservoir, through a sample line, through the cuvette, through a waste line, and into to a waste container.
