75W 1550nm Fiber Coupled Diode Laser

The 1550nm laser will be absorbed by the lens and cornea of the human eye and will not cause damage to the retina. The 1550nm laser radar can emit higher power and the detection distance can be farther.

However, the 1550nm lidar cannot use conventional silicon absorption, and needs to use the more expensive indium gallium arsenide (InGaAs) material
