Laser classes are categories assigned to lasers based on their potential to cause harm to humans, particularly to the eyes and skin. The classification system is designed to indicate the level of risk associated with the laser's power output and wavelength, guiding the necessary safety precautions for their use. The classes range from Class 1 (safest) to Class 4 (most hazardous).Class 1: Safe under all conditions of normal use. Used in CD/DVD players, laser printers, barcode scanners. No special precautions needed.Class 1M: Safe except when viewed with optical instruments. Used in fiber optic systems, measurement tools. Avoid using optical instruments to view the beam.Class 2: Safe for brief exposure due to blink reflex. Used in laser pointers, alignment lasers. Do not stare into the beam.Class 2M: Safe for brief exposure unless viewed with optical instruments. Used in alignment tools, rangefinders. Avoid using optical instruments to view the beam.Class 3R: Low risk of injury, up to 5 mW. Used in laser pointers, alignment lasers. Avoid direct eye exposure.Class 3B: Can cause eye and skin injuries, up to 500 mW. Used in research, some medical devices. Use safety goggles and avoid direct exposure.Class 4: High risk, can cause severe injuries and fire hazards, above 500 mW. Used in industrial cutting, welding, medical, research. Use protective equipment and follow strict safety measures.

Fiber LasersHigh-efficiency lasers using doped optical fibers; excellent beam quality, used in cutting, welding, and telecommunications.Continuous Wave (CW) LasersEmit steady, uninterrupted beams; used for continuous material processing and research, require robust cooling.Pulsed LasersEmit high-energy bursts; ideal for precision applications like micro-machining, engraving, and medical procedures.Fiber Pulsed LasersCombine fiber laser efficiency with pulsed operation; used for precise tasks in micro-machining, engraving, and medical fields.Gas LasersUse gases like CO2 or helium-neon; high beam quality, common in cutting, engraving, and scientific research.Solid-State LasersUse solid gain media like crystals or glass; versatile applications including medical procedures, material processing, and laser ranging.Dye LasersUse liquid dyes as the gain medium; tunable wavelengths, used in spectroscopy and medical treatments.Semiconductor Lasers (Diode Lasers)Compact, efficient lasers using semiconductor materials; common in communications, barcode scanning, and laser printing.
