Complementary Wavelengths

Designed to work synergistically, offering optimal treatment options for both hard and soft tissues. The Er:YAG laser is ideal for precise hard and soft tissue ablation, while the Nd:YAG penetrates deeper, perfect for applications like periodontal treatment.

Digital Pulse Technologies

Fotona® offers cutting-edge digital pulse technologies — VSP, ASP, and QSP™ — that enhance laser precision and efficiency. VSP technology delivers consistent, square-shaped pulses, minimizing heat buildup and ensuring patient safety. ASP builds on VSP by adapting pulse durations for optimal tissue interaction, boosting treatment effectiveness. Meanwhile, QSP™ improves hard-tissue ablation, ensuring sharper cuts and smoother finishes for better clinical outcomes. Together, these innovations set a new standard in dental laser performance, enabling faster, more precise procedures with minimal thermal impact.

Solid Crystal Lasers

Fotona LightWalker® “gold standard” laser wavelengths are produced by solid crystal lasers that can significantly outperform diode lasers in terms of peak power and range of pulse durations. Up to 1,000× higher peak power compared to diode lasers and engineered pulse shapes provide superior disinfection and the impressive benefits of photobiomodulation.

Inside the Technology

Energy Feedback Control

Fotona LightWalker® incorporates a sophisticated double channel safety structure for energy regulation, which contributes to procedure safety. The laser output energy is constantly regulated by a signal from two energy meters.

Intuitive Touchscreen Display

Designed for ease of use, the high-resolution touchscreen offers an intuitive interface with seamless navigation. Pre-set treatment parameters, real-time monitoring, and responsive controls ensure precision, efficiency, and a streamlined workflow for every procedure.

Advanced Handpiece Technology

Equipped with a range of smart handpieces, the system offers versatility across multiple applications. Each handpiece is designed for specific treatments, enabling practitioners to customize procedures for optimal patient outcomes. The handpieces facilitate a variety of laser modalities, enhancing the system’s adaptability and performance.

OPTOflex^® Articulated Arm

The OPTOflex^® articulated arm ensures efficient, distortion-free laser beam delivery to the treatment site. Its lightweight, compact design enhances maneuverability, allowing for precise targeting during procedures. The arm’s foldable structure reduces system height for convenient storage and adaptability in various clinical settings.

The Fotona LightWalker^® is the easiest, most efficient, clean-cutting laser I have ever used. Having both the Er:YAG and Nd:YAG wavelengths in one system easily allows you to switch from one procedure to another at the touch of a button.”

Dr. Mark Colonna

The new AT is by far superior to all of them! The QSP pulse mode allows me to ablate enamel on par with my high-speed handpiece (1st time ever!!) I have yet to use any anesthetic this week on any laser patient. Class 1, 2, 3, 4, and 5’s!! In addition, the new green aiming beams light up the target, creating great contrast with the colors of natural tissue. I foresee a paradigm shift in my laser practice with Fotona^®and Fotona LightWalker^®!”

Dr. Rick Cardoza

It’s so much more enjoyable to practice with a laser. You can’t buy that. Well, you do have to purchase the laser, but it’s sort of a you can’t buy happiness sort of thing.”

Dr. Lorraine Patten

This is the only dual-wavelength laser on the market, and I have been so happy with my consistent results using the Fotona^® laser. Most impressive is its ability to treat peri-implantitis. To me, this laser has provided the ability to remove debris from the implant surface to graft without altering the implant or causing metalosis in the sulcus”

Hana C. Hobbs

When I was in the chaotic process of setting up my office to focus on Airway Sleep Dentistry, I knew that Fotona LightWalker^® was one of the most—if not the most—important pieces of equipment I needed to bring that vision to life. The ability to help our patient base solely through the Fotona NightLase^® procedure was what would set us apart…”

Dr. Keith Gressell

The Fotona^® laser is an absolute game-changer! It all started with my dentistry — I loved using it for my restorative work, practicing small Class I composites and pain-free dentistry. Then, it expanded to my hygienists using it during their SRP cleanings. And now, it has evolved into a key tool for all facial esthetics!”

Dr. Noor A. Khaki

What I love about the Fotona LightWalker^® is that I can perform procedures on primary teeth and anterior adult teeth without needles, and most small posterior teeth can also be treated without anesthetic. It’s just as fast as drilling, but the comfort it provides to patients is incredible. Parents are thrilled, and patients love it! Appointment times have decreased significantly, soft tissue procedures are quicker and easier…”
