Item Name
4W 1550nm Single Emitter Diode Laser Chip Sensing Lidar
The "single emitter" designation indicates that the laser is constructed with a single diode chip, rather than an array of diodes. This allows for a more focused beam, with a narrower divergence angle and higher beam quality. Laser chips are widely used in various applications such as telecommunications, fiber optic communications, laser printing, barcode scanning, medical procedures, and many more. They are preferred over other light sources due to their compact size, high efficiency, and precise control.
