Laser: meaning, definitions and examples

This term is most commonly used in technology and science contexts, specifically when referring to devices that emit a concentrated beam of light through the process of optical amplification. It is often used in medical procedures, industrial applications, telecommunications, and entertainment.

• The surgeon used a laser to perform the eye surgery.
• Laser cutting machines can slice through metal with high precision.

This is a more general term that simply refers to any stream of light particles. It can be used in everyday situations, as well as in scientific and technical descriptions. It is less specific than 'laser' and doesn't necessarily imply the technological aspect.

• A beam of light shone through the window.
• The lighthouse sent out a beam of light to guide the ships.

This phrase is often used in physics and engineering to describe a device or process that increases the intensity of light. It is more technical and might be found in scientific literature or discussions regarding the enhancement of light frequency or intensity.

• Scientists are researching new materials for light amplifiers.
• The project aimed to develop a more efficient light amplifier for optical communications.

Scientific, medical, and technological contexts. Often used when describing a device that emits a focused beam of light.

• The doctor used a laser to precisely cut the tissue
• The construction team used a laser level to ensure the wall was straight

General contexts where a beam of light is described. It can be used for both natural and artificial light sources.

• A light beam shone through the dense fog, guiding the ships towards the shore
• The party was lit up with vibrant light beams from various colors

Technical contexts usually referring to a device or system that generates light. It may imply something more complex than a simple flashlight.

• The light generator was essential for the night-time construction work
• Emergency services often require a portable light generator for nighttime operations

Can also be used metaphorically to refer to someone's intense focus or precision.

• His laser-like attention to detail ensured the project’s success.
• With a laser focus, she zeroed in on the problem.

Used to describe a high level of mental or visual focus on a specific task or object. This phrase is flexible and can be used in various situations, from academics to everyday activities.

• During the exam, she focused intensely on each question.
• He focused intensely on the screen, trying to decode the message.

Typically employed to describe someone directing their attention or mental effort with great intensity. Often used in educational or work-related scenarios.

• You need to concentrate sharply if you want to solve this complex math problem.
• He concentrated sharply on the details of the project.
