High Performance 808nm 200mW IR Laser Diode for Industrial Use
QSI 808nm 200mW laser diode grown via MOCVD with a quantum well structure to deliver reliable, consistent light output — making it an ideal light source for optoelectronic applications like solid-state laser pumping, medical use, and industrial systems.
Operating at a precise 808nm wavelength, it provides a steady 200mW continuous-wave (CW) optical output, paired with TE polarization (electric field parallel to the junction plane) for optimized compatibility with polarization-sensitive setups. Housed in a compact TO-18 (φ5.6mm) package, it balances small form factor with robust performance, simplifying integration into space-constrained devices.
Engineered for versatility, this laser diode excels in demanding scenarios: its quantum well structure ensures efficient energy conversion, while its stable emission and compact design make it suitable for both medical equipment (where precision matters) and industrial systems (where durability is key).
Whether powering solid-state laser pumps, medical devices, or industrial optoelectronic tools, the QSI 808nm 200mW laser diode combines advanced quantum well engineering, reliable performance, and flexible packaging — a trusted solution for high-demand applications.
