Long Description
This project involves the development and manufacturing of high-power semiconductor lasers, which are crucial in various applications such as industrial cutting and welding, medical treatments, and telecommunications. The design phase would encompass selecting the appropriate semiconductor materials, such as gallium arsenide (GaAs) or gallium nitride (GaN), and determining the laser's architecture, including the type of laser (e.g., edge-emitting laser or vertical-cavity surface-emitting laser (VCSEL)), the cavity design, and the integration of optical components for beam shaping and control. Fabrication would involve the use of advanced semiconductor manufacturing techniques, including epitaxial growth (e.g., molecular beam epitaxy or metalorganic chemical vapor deposition), lithography, etching, and doping processes to create the laser diodes. Additionally, the project would require the development of efficient cooling systems to manage the heat generated by high-power operation, as well as testing and characterization to ensure the lasers meet the required performance specifications, including output power, beam quality, and reliability.
