[hide]Introduction
Laser is widely used in medical treatment, military, and other fields due to its good directivity and energy concentration. The Laser Transmitter module, as the name suggests, is a one that can emit laser.
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. Lasers differ from other sources of light because they emit light coherently.
Spatial coherence allows a laser to be focused to a tight spot, enabling applications like laser cutting and lithography, and a laser beam to stay narrow over long distances (collimation), enabling applications such as laser pointer. Lasers can also have high temporal coherence which allows them to have a very narrow spectrum, i.e., they only emit a single color of light. And its temporal coherence can be used to produce pulses of light—as short as a femtosecond.
The schematic diagram of the module is as follows:
