QSI TO5 9mm Package 808nm 500mW IR Laser Diode for Material processes
This QSI 808nm 500mW continuous-wave (CW) laser diode is a high-performance optoelectronic component, engineered to deliver robust, stable emission for demanding applications like solid-state laser excitation, medical use, material processing, and precision measurement.
Operating at a typical 808nm wavelength (ranging 803–813nm), it provides a consistent 500mW CW optical output — paired with TM polarization (electric field perpendicular to the junction plane) for optimized compatibility with specialized optical setups. Housed in a TO-5 (φ9mm) package (a larger form factor that supports efficient heat dissipation for high-power operation), it balances durability with reliable performance.
Designed for efficiency, it features a 100mA typical threshold current, 550mA typical operating current (at 500mW output), and 2.2V typical operating voltage — ensuring optimized energy conversion. Its controlled beam divergence (8° parallel, 30° perpendicular typical) and tight beam angle tolerance enhance precision for targeted applications.
Built to withstand varied conditions, it functions across a -10 to +40°C operating temperature range and tolerates -40 to +85°C during storage, with a 2V reverse voltage rating (30V for the integrated photodiode). Whether powering high-intensity laser systems, medical devices, or industrial processing tools, this QSI 808nm 500mW laser diode combines high power, stable performance, and durable packaging to meet the demands of advanced optoelectronic applications.
