Complete List of Multilayer Laser Diode Models

Multilayer and multi-mode laser diodes are available across a wide range of wavelengths, powers, and packages from multiple manufacturers, with detailed specifications accessible through specialized databases and suppliers.

Overview of Multilayer Laser Diodes

Multilayer laser diodes, often referred to as multi-mode or broad-area diodes, are semiconductor devices designed to emit high-power laser light with multiple transverse modes. They are widely used in material processing, medical applications, fiber laser pumping, LIDAR, and sensing. Key specifications include:

• Wavelengths: Typically 375 nm to 2000 nm for standard diodes, with Quantum Cascade Lasers (QCLs) and Interband Cascade Lasers (ICLs) extending to 3–11 µm .
• Output Power: From milliwatts to tens of watts in continuous wave (CW) or pulsed operation .
• Packages: TO-can, butterfly, C-mount, flatpack, fiber-coupled modules, and chip-on-submount .
• Stripe Widths: 100–400 µm for broad-area diodes, affecting beam structure and power .
• Applications: Laser pumping, medical procedures, material processing, LIDAR, and defense systems .
