solid-stateinfrarednear-infrared

Overview
The Excelitas TPG3AU1S04 is a 905 nm pulsed edge-emitting laser diode delivering a peak optical output of 54 W at 18 A. With a 100 × 10 µm emission aperture and a 10 V forward voltage, it is engineered to provide consistent beam performance and efficient thermal behavior for mid- to long-range ToF and LiDAR systems.

Product details
The TPG3AU1S04 occupies a performance niche between compact and ultra-high-power pulsed lasers. Its triple-cavity design and wide emission aperture ensure uniform beam profile and improved thermal dissipation during prolonged high-load operation. The 10 V forward voltage supports lower system power consumption while maintaining strong signal return for extended-range sensing.
