Which type of laser is frequently utilized in medical applications?

The selection of Class 3B and Class 4 lasers is appropriate as these types of lasers are commonly employed in medical applications. Class 3B lasers are capable of causing harm to the eye with direct exposure, and they are used in various medical procedures, including certain surgical applications and treatments. These lasers can produce sufficient energy to be effective in altering tissues, making them suitable for applications such as skin resurfacing and various forms of laser surgery.

Class 4 lasers are even more powerful and are used in significant medical interventions, including laser surgery, photocoagulation, and tissue ablation. Due to their high energy output, they can be used to cut or vaporize tissue, making them invaluable in surgical settings. This makes them essential in various fields such as ophthalmology, dermatology, and oncology.

In contrast, other classes of lasers, such as Class 1 and Class 2, are considered safe under normal operating conditions and are generally not used for therapeutic purposes. Class 1 lasers are low-powered and do not pose a risk of injury, while Class 2 lasers are only marginally more powerful and also present minimal hazard. Class 5 lasers do not exist in the standard classification system. Therefore, Class 3B and Class
