Laser systems operate across a broad range of wavelengths, each suited to different applications. Understanding common laser wavelengths can help users identify appropriate laser safety eyewear.

One of the most widely used wavelengths is 1064nm, found in Nd:YAG and fiber laser systems. These lasers are commonly used for welding, cutting, marking, cleaning, and medical procedures.

755nm Alexandrite lasers are frequently used in cosmetic and dermatological treatments. 810nm diode lasers are common in both medical and industrial applications.

532nm green lasers are widely used in laboratories, alignment systems, and research environments due to their high visibility.

10,600nm CO₂ lasers are commonly found in surgical systems, engraving equipment, and industrial processing machines.

Because each wavelength interacts differently with laser safety filters, protective eyewear should always be selected based on the laser specifications rather than appearance alone.
