- Laser - Wikipedia
Laser A telescope in the Very Large Telescope system producing four orange laser guide stars A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation
- Laser | Definition, Acronym, Principle, Applications, Types | Britannica
Laser, a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation The emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths
- What Are Lasers And How Do They Actually Work? - ScienceAlert
How do lasers do laser stuff? The beating heart of lasers are materials that give parts of the electromagnetic spectrum a boost of energy as they pass through This boost is referred to as ' gain ', and can effectively amplify the light's power Behind this amplification is a process called stimulated emission

- Lasers: Understanding the Basics - Photonics
The laser cavity The laser cavity, or resonator, is at the heart of the system A single transit through a collection of excited atoms or molecules is sufficient to initiate laser action in some high-gain devices such as excimer lasers; however, for most lasers, it is necessary to further enhance the gain with multiple passes through the laser medium This is implemented along an optical axis
