Photonics Dictionary

laser output: The laser output refers to the generated and emitted light produced by a laser system. This output is characterized by several key properties that distinguish lasers from other light sources. These properties include:

Coherence: Laser light is coherent, meaning that the emitted photons have the same frequency and phase, resulting in a well-defined and synchronized beam. This coherence allows for the formation of a tight, focused beam of light.

Monochromaticity: Laser light is typically monochromatic, meaning it consists of a single color or wavelength. This characteristic is a result of the specific energy transitions within the lasing medium, leading to the emission of photons at a particular frequency.

Collimation: Laser beams are highly collimated, meaning that the light waves travel parallel to each other with minimal divergence. This property enables lasers to maintain their focus over long distances.

Intensity: Laser light is often characterized by high intensity. The concentrated photons in a laser beam contribute to its brightness and the potential for precise energy delivery to a target.

Directionality: Laser output is directional, meaning the emitted light travels in a specific direction. This directionality is a result of the mirrors within the laser cavity that cause the photons to be reflected and amplified in a controlled manner.

Polarization: Laser light can be polarized, meaning that the electric field oscillates in a specific direction. The polarization of laser output can be manipulated for various applications.

The specific characteristics of the laser output depend on the type of laser, the lasing medium used, and the intended application. Different lasers are designed to emit light at specific wavelengths and with tailored properties to suit their purpose, whether it's for medical procedures, industrial applications, research, or other fields.
