What type of laser is specifically known for causing thermal injuries?

The classification of lasers is based on their potential to cause harm to the eyes and skin. Class 4 lasers are particularly known for their ability to cause thermal injuries due to their high output power and ability to produce significant amounts of heat. These lasers can not only cause immediate damage to eye tissue but can also ignite materials, leading to fires or other hazards.

The potential for thermal injuries arises because Class 4 lasers emit wavelengths that can penetrate biological tissue and generate heat, resulting in burns. This risk makes the presence of Class 4 lasers subject to stringent safety protocols, including controlled access areas and the use of appropriate personal protective equipment. Considering their ability to cause serious injuries, Class 4 lasers are classified as high-risk devices that require specific safety measures during operation.
