What frequency does a class 4 laser operate at?

Class 4 lasers are defined as high-power lasers that can emit powers greater than 500 milliwatts (0.5 watts). These lasers pose significant risks to eyes and skin, and they require stringent safety measures to prevent accidents and injuries. The classification hinges on the output power, with any laser exceeding this threshold categorized as a Class 4.

Class 4 lasers are known to be used in various applications including medical procedures, industrial cutting, and research, where their high intensity is necessary. Understanding the threshold for Class 4 lasers is crucial for anyone operating or working in proximity to these devices, as it directly relates to safety protocols that must be observed. These lasers can result in severe eye damage, skin burns, and can also create fire hazards, making awareness of their classification and operational parameters essential for safety.
