Over the past decade, light-emitting diodes (LEDs) have revolutionized the field of lighting. However, they present limitations for applications requiring high optical power density. Laser diodes (LDs), which are more efficient and compact, offer a promising alternative. Operating through stimulated emission amplification, they are significantly more efficient at high power levels. In addition, their lower beam divergence allows for better beam manipulation and direction.
The project led to the development of an optical module based on laser diodes, producing a collimated white light beam with a diameter of 9 mm and an angular aperture of approximately 8 degrees.
