The LDX-2810-680 is a high-power multimode laser diode chip from LDX Optronics Inc., engineered for applications demanding low divergence, high brightness, and proven reliability. Operating at a central wavelength of 680 nm with a ±3 nm tolerance, it delivers up to 800 mW of output power in free space mode or 640 mW when fiber coupled, alongside high efficiency and a spectral width of 1.5 nm. This makes it ideal for diverse markets including medical treatments, industrial processing, scientific research, and military systems. Custom wavelengths, packaging, and designs are available to meet specific needs, ensuring versatility across various integrations.

The laser is offered in a wide array of free space and fiber-coupled packages for seamless deployment. Free space options include exposed emitter types like C-mount, B-mount, and chip-on-submount (using materials such as copper or BeO for heatsinking), as well as hermetically sealed windowed packages like 9mm, TO-3 (with TEC, thermistor, and photodiode), and HHL. Fiber-coupled variants, achieving over 80% efficiency, encompass 9mm SMA FC (with photodiode and isolated package), 8-pin BFC (with thermistor), 2-pin FCP, and HHL-FC. Additional features like fast-axis collimation (FAC) lensing provide less than 1° divergence or matched beam shaping, enhancing optical performance.
