Which of the following systems is characterized by being Monochromatic, Coherent, Highly Directional, and High Intensity?

The system characterized by being monochromatic, coherent, highly directional, and high intensity is indeed a laser.

Monochromatic refers to the emission of light at a single wavelength, which is a fundamental property of lasers. This singular wavelength allows for very specific applications in various fields, including communications, medical procedures, and cutting technologies.

Coherence is another key characteristic, meaning that the light waves emitted by a laser are in phase with each other, which contributes to the sharpness and precision of the laser beam. This quality makes lasers particularly effective for applications like holography and precision measurements.

Being highly directional indicates that a laser beam can travel long distances with minimal spread, making it suitable for applications where focused energy output is needed, such as targeting or navigation.

Lastly, high intensity means that lasers can emit a substantial amount of energy in the form of light, allowing for powerful applications in cutting and communication technologies.

In contrast, radar systems operate over a range of wavelengths and produce signals that are not coherent, while FLIR (Forward Looking Infrared) and low-light TV systems rely on the detection of light in varying conditions and are not characterized by the same properties as lasers. Therefore, lasers uniquely fulfill the specified characteristics of being monochromatic,
