Laser Sources

Laser sources are devices that produce a concentrated, coherent beam of light through a process called stimulated emission. Unlike regular light bulbs, laser light is highly focused, monochromatic (single wavelength), and can travel long distances without spreading out. This precise and powerful light is used in applications like medical treatments, communication systems, barcode scanners, and measurement instruments. Lasers come in various types, such as solid-state, gas, and semiconductor, each suited for specific uses depending on their light properties and power levels.
