Laser Power Laser power refers to the rate at which energy is emitted or delivered by a laser beam and is typically measured in watts (W) or milliwatts (mW). Laser power is a fundamental parameter that determines the intensity, brightness, and effectiveness of a laser beam for various applications such as cutting, welding, engraving, marking, illumination, and optical pumping. The power output of a laser depends on factors such as the laser medium, pump source, cavity design, optical losses, and operating conditions.
Lasers can be classified based on their power output into different classes, ranging from low-power lasers used in consumer electronics and barcode scanners to high-power lasers used in industrial materials processing, medical surgery, and scientific research. Accurate measurement and control of laser power are essential for optimizing performance, ensuring safety, and achieving desired outcomes in laser-based systems and applications. |
