Laserluokitusten, often translated as laser classification, is a system used internationally to categorize lasers based on their potential for causing harm to people and property. This classification is crucial for safety regulations and is primarily determined by the laser's power output, wavelength, and beam characteristics. The most common classification system is the IEC 60825 standard, which is widely adopted globally.

The IEC 60825 standard divides lasers into several classes, typically ranging from Class 1 to Class 4. Class 1 lasers are considered safe under normal operating conditions, posing minimal risk of injury. Class 1M and Class 2 lasers are also relatively low risk, with Class 2 lasers relying on the natural blink reflex to protect the eyes. Class 3R lasers present a moderate risk, and direct eye exposure can cause damage. Class 3B lasers are hazardous if viewed directly and can cause serious eye injury, but diffuse reflection is generally not hazardous. Class 4 lasers are the most dangerous, capable of causing severe eye and skin damage, and can also pose fire hazards.

Understanding laser classification is vital for manufacturers, users, and regulators to implement appropriate safety measures. These measures can include warning labels, protective eyewear, interlocks, and restricted access to areas where high-power lasers are operated. The goal of laser classification is to ensure that the risks associated with laser use are adequately identified and managed to prevent accidents and injuries.
