Laser Class 4 – What Does It Mean?

The term “laser class 4” refers to the highest risk category within laser classification. Many professional lasers used in clinics fall into this category.

For clinics, it is important to understand what the classification means in practice.

What is laser classification?

Laser classification is typically done according to the IEC 60825-1 standard. The classification indicates the level of risk based on power and potential exposure.

Class 4 is the highest category and includes lasers that:

• Has high impact
• May cause eye damage from direct or reflected radiation
• May cause skin damage if used incorrectly
• Requires controlled safety procedures

What types of clinical equipment are class 4?

Many professional diode and picosecond lasers are classified as Class 4.

What does class 4 mean for the clinic?

Class 4 involves requirements for:

• Safety glasses
• Access control
• Warning signs
• Documented procedures
• Risk assessment

Technology and effect

Classification depends on, among other things:

• Power (Watts)
• Pulse duration
• Wavelength
• Beam profile
