Product Description

LightWalker lasers are designed for dental perfectionists and all forward-thinking professionals who wish to upgrade their daily dental experience with new treatment possibilities that only the latest laser technology can offer. Following its launch, Fotona’s LightWalker dental laser system quickly earned widespread industry acclaim and highly respected technology and innovation awards.  LightWalker’s patented QSP (quantum square pulse) mode represents an important technological advancement, improving the laser’s interaction with dental tissues for optimized patient comfort, speed and clinical result.

High Performance Dentistry, Without Compromises

LightWalker’s state-of-the-art design, engineering and patented technologies have made it the world’s fastest-cutting Erbium laser, outperforming even rotary burs in terms of speed and precision, while simultaneously offering a wide range of highly effective hard- and soft-tissue treatments. LightWalker’s easy-to-select operating modes and advanced laser-beam delivery systems enhance the precision and performance of each laser treatment for optimal clinical efficacy.

Broad Spectrum of Effective and Easy-to-Perform Applications

From conservative dentistry, endodontics and implantology to periodontics and soft-tissue surgery, LightWalker lasers offer the most comprehensive list of clinical applications of any dental laser made today. LightWalker is also perfect for cosmetic dental procedures such as Fotona’s gentle but highly effective TouchWhite laser tooth whitening. And with an optional aesthetic upgrade, the LightWalker AT / AT S model can even be used for facial skin treatments, such as wrinkle reduction.

Typical treatment procedures with LightWalker are faster, easier to perform and with less pain and shorter healing times compared to conventional treatments.

Two Models to Choose From:

  • LightWalker AT / AT S is the most advanced and highest performance LightWalker model. It comes equipped with high-performance Er:YAG and Nd:YAG lasers, a state-of-the-art OPTOflex® articulated arm, an unrivaled 20 W of power and Fotona’s patented QSP pulse technology for ultimate performance and treatment precision.
  • LightWalker ST-E is a single-wavelength, Er:YAG only laser system, designed for dentists who already have a soft-tissue laser or who prefer to focus mainly on hard-tissue treatments.

LightWalker Features:

Complementary Wavelength Combination – for Enhanced Results

Each LightWalker model is a technologically advanced system built from the ground up with the most state-of-the-art and reliable technologies available. LightWalker’s “gold standard” dental laser wavelengths (1064 nm and 2940 nm) are produced by solid state crystal laser sources. With the choice of two complementary wavelengths (in terms of their effect on tissues) LightWalker comes very close to being a true “optimal” laser. Virtually all laser-assisted dental treatments can be performed with either the highly absorbed Er:YAG laser wavelength or the deeply penetrating Nd:YAG laser wavelength.

Latest Pulse Technologies – for Exceptional Performance

Fotona’s proprietary VSP (Variable Square Pulse) and SMOOTH technologies raise the precision, performance and safety of dental laser treatments to the highest level. VSP allows practitioners to precisely control the laser pulse duration and its fluence according to the needs of the specific application, at the simple touch of a button.

Fotona’s patented QSP (Quantum Square Pulse) mode* allows the laser to ablate more efficiently and with greater precision. The improved ablation efficacy of QSP mode indicates that more of the laser energy is used for cutting and less is absorbed by the interfering debri or sub-ablation threshold of the surrounding dental tissues. This provides the means for improved cutting speed, finesse and comfort when treating hard and soft dental tissues.

LightWalker is also able to produce exceptionally low-energy laser pulses optimized to generate a clinically effective photoacoustic effect for endodontic treatments using the photon-induced photoacoustic streaming treatment protocol.

Exceptional Laser Power – for the Fastest Working Speed

Up to 20 W* of Er:YAG laser power provide an exceptionally wide range of fast, safe and effective treatment options. In addition to dental applications, LightWalker also offers the power and capability to provide a broad range of aesthetic treatments using the same laser system.

Ultimate Peak Powers – for Improved Effectiveness

Up to 1000× higher pulse power compared to diode lasers provides for improved tissue selectivity and treatment effectiveness.

Online Energy Monitoring – for Safety Without Compromise

LightWalker systems come equipped with laser pulse monitoring systems based on DET (Dual Energy-meter Technology) to assure 100% accuracy. Combined with Fotona’s EFC (Energy Feedback Control) technology it assures consistency of laser pulse output for unrivaled safety during the entire lifetime of the product.

X-Runner –  for New Treatment Possibilities

LightWalker AT / AT S is the first Erbium dental laser on the market with digitally controlled handpiece technology, offering dentists entirely new treatment possibilities and unmatched levels of precision that have not been seen before in the world of dentistry.

OPTOflex® Articulated Arm – for Weightless Operation

The LightWalker AT’s unique and patented OPTOflex® articulated arm is perfectly balanced during use, making Er:YAG handpieces feel completely weightless in your hand. OPTOflex® allows for a full range of motion and a maximum degree of control as it makes maneuvering handpieces much smoother, improving treatment precision and ease.

Titanium  Handpiece Technology – for Unmatched Durability

All LightWalker models feature advanced titanium handpieces that provide robust durability for constant handling and frequent sterilization. Lightwalker’s tipped and tipless Er:YAG handpieces have an integrated air/water spray with adjustable water temperature for additional patient comfort, as well as a quick disconnect system for greater convenience and easier sterilization. More than 15 specialized handpieces are compatible with LightWalker systems.

Green Pointing Beam – for Improved Visibility

Introduced with dental surgeons in mind, this optional feature for LightWalker AT S helps provide improved visibility over standard red-pointing beams when performing oral surgery.

Automatic Handpiece Detection – for Ease of Use

The LightWalker AT / AT S comes equipped with two Nd:YAG handpieces, providing two different fiber diameters constantly available at your disposal. What’s more, LightWalker AT has an automatic handpiece detection system which knows exactly which handpiece you have picked up and automatically restores the last-saved parameters for that handpiece.

Over 40 Preset Treatments – for Ultimate Simplicity

The LightWalker touch-screen offers a simple & intuitive menu of pre-programmed laser treatments. You pick the treatment and the laser automatically sets your optimum starting parameters. With an optional dermatological handpiece, the AT / AT S model can even perform aesthetic skin treatments such as wrinkle removal and skin rejuvenation (where permitted by local practice regulations).
