10W 850nm Pulsed VCSEL Diode

Vertical Cavity Surface Emitting Laser (VCSEL) has a complex semiconductor structure, but its packaging structure is generally simpler. Unlike edge-emitting laser diodes, EEL needs to be cleaved into bars to detect whether it is good or not, while VCSEL can detect the chip before packaging and screen the product, greatly reducing the risk cost of the product. There are three inspection processes in the VCSEL production process, and all three processes require a pulse current source to test the device. A fast, flexible and high-precision test solution is crucial to reducing the cost of testing.
