What type of laser is often used in medical applications?

Class 3B lasers are commonly used in medical applications due to their specific characteristics, such as being powerful enough to perform procedures effectively while still managing safety protocols. These lasers can operate at various wavelengths and are suitable for precise surgical tasks, including laser surgery, dermatological treatments, and phototherapy.

The application of Class 3B lasers in medical settings also stems from their ability to provide controlled energy that can target tissue effectively with minimal damage to surrounding areas. While Class 4 lasers are indeed powerful and have some medical applications, they require more stringent safety measures due to their high energy output, which can also pose a greater risk to both the operator and patients. Class 1 and Class 2 lasers are typically less powerful and are mostly used for lower-risk applications, thereby limiting their medical utility.
