Laser Tube A laser tube, also known as a laser resonator or laser cavity, is a key component of a laser system responsible for generating and amplifying coherent light through the process of stimulated emission. A laser tube typically consists of a sealed enclosure containing a gain medium, such as a gas mixture or solid-state material, optical elements, and mirrors that form an optical cavity.
When energy is applied to the gain medium, it emits photons that bounce between the mirrors, stimulating further emission and amplification of light until a coherent laser beam is produced. Laser tubes come in various types, including gas lasers (such as CO2 lasers and helium-neon lasers) and solid-state lasers (such as diode-pumped lasers and fiber lasers), each with specific properties, applications, and operating principles. Laser tubes are fundamental components of laser systems used in diverse fields such as materials processing, telecommunications, medical devices, and scientific research.
