MLS Laser Therapy helps overcome the painful symptoms typical of musculoskeletal disorders which means patients return to everyday activities faster.


    • Reduction in pain

      Reduction in pain from pathology, trauma, iatrogenic, pre-operative and post-operative.

    • Reduction in oedema

      Reduction and prevention of oedema associated with disease, injury or potentially post-treatment. Can be used to ameliorate or prevent oedema.

    • Biostimulation

      Promotes improved healing of soft and hard tissue damage caused by pathology or post-operative.

    • MLS Difference

      The MLS laser achieves it results through the use of a combination of a superpulsed 905nm wavelength laser synchronised with the continuous wave of a 808nm laser.

      • Effective Treatment

        The synchronised dual-wavelength delivery system provides synergistic results so that pain reduction is greater than with the equivalent single wavelength beam.

        For the practitioner, this means the effective treatment of pain, inflammation and oedema in the one treatment session.

      • Reduces inflammation and oedema

        While the 905 superpulsed laser is treating pain and promoting healing, the continuous beam 808nm wavelength simultaneously reduces inflammation and oedema.

        The 905 laser is a true superpulsed laser in contrast to many pulsed lasers that are merely chopped (turned on and off).  The pulse rate of the MLS® laser is so rapid that the treatment area never heats up no matter how long the treatment is for. It makes MLS® laser perfectly safe.

    • What is a Multi Wave Locked System?

      The Multiwave Locked System (MLS®) is a new patented LLLT system that combines 905nm pulsed emissions with 808nm continuous emissions.

    • It was developed by ASA Laser to help overcome some of the limitations on previous LLLT systems. The aim is to produce simultaneous actions on pain, inflammation and oedema. With the MLS® system it is possible to achieve strong anti-inflammatory, anti-oedema and analgesic effects simultaneously and in a short period of time.

      The unique synchronised laser beam delivers a balance of the two wavelengths and powers providing safe and effective delivery. The optical design of the delivery system transfers energy up to 3 – 4 cm deep to effect tissue at a cellular level. The synchronised wave results in a synergistic effect where both the analgesic and anti-oedema effects are greater than if two single lasers had been used.


    • 905nm superpulsed emission

      Fast acting analgesia and accelerated healing.

      The high-power pulsed laser 905 nm emission produces an analgesic effect.

      It has also been shown to significantly increase the activity of mitochondrial respiratory chain complexes I, II, III, IV and succinate dehydrogenase, thus suggesting that this emission may induce an increase in ATP synthesis that may accelerate the healing processes.

    • 808nm continuous emission

      Anti-oedema and increased cell energy.

      The 808nm continuous emission has an immediate ant-inflammation and anti-oedema effect. In addition, the 808 nm wavelength falls in the secondary absorption peak of cytochrome oxidase, therefore it is expected to activate mitochondria thus favouring ATP production.

    • Traditional
      Laser Scanning

      In traditional scanning, reflection is greater since the divergence angle of the Laser beam is great.

      In traditional scanning, the coverage area is not homogeneous: beams overlap on the sides, while in the central zones some parts are not reached by the radiation.

    • MLS® Laser Therapy

      In the multitarget modality the inclination of light beam is smaller, therefore also side reflection is small.

      The multitarget modality “Greek key” movement guarantees the homogeneous coverage of the treatment area. There is no overlapping, and the whole area is reached by the radiation.

    • Compared to Traditional Laser
      Non-homogeneous Tissue Lighting

      Light distribution is homogeneous (much more than in traditional scanning laser devices), all the photoreceptors of the area to be treated are promptly activated thanks to an optimal energy dose; a great tissue volume is activated at the same time.

      • Why is MLS® different?

        The MLS® laser produces a combination of synchronised pulsed and continuous waves and is therefore effective in treating pain, inflammation and oedema in the one treatment session.

        Synchronised dual-wavelength beam provides synergistic results – e.g. pain reduction is greater than with equivalent single wavelength beam. So, while the 905 superpulsed laser is treating pain and promoting healing, simultaneously the continuous beam 808nm wavelength is helping to reduce inflammation and oedema.

        A combination of the high-power laser system and the synergistic effect of the dual wavelength MLS® results in fast treatment times – 3 to 10 minutes with the benefits often evident from first application.

      • When can it be used?

        MLS® high powered system means reduced number of treatments. MLS® laser therapy is an ideal non-invasive, non-threatening, pain free and safe treatment modality that perfectly complements and benefits many treatment regimes.

        It is suitable for use before, during and after a wide variety of procedures to enhance outcomes and improve patient satisfaction and comfort.

        Use the MLS® treatment in a preventive capacity to reduce post-operative symptoms and complications by reducing pain, inflammation, swelling and promoting healing. Use the MLS® therapy to provide a noticeable reduction in many types of presenting pain at the first appointment in a short period of time (3-10 minutes).

      • Where can it be used?

        The built-in software for the Mphi laser product range contains multiple built in settings for a variety of pathologies. MLS® Laser Therapy helps overcome the painful symptoms typical of musculoskeletal disorders which means patients return to everyday activities faster. It represents a valuable tool for rehabilitation, as it effectively promotes the recovery of functions that were compromised by surgery or fractures.

        The MLS® Laser Therapy can be used in a scanning mode to treat whole muscle groups associated with pathology.  Additionally, it can be localised to target various trigger points. In both cases, pre-set treatment regimens are programmed into the built-in software. It is indicated for the treatment of pain and muscle spasms, joint stiffness, arthritis pain and it promotes an increase of blood circulation and muscle relaxation.

        Treatment sites also include muscles of the musculoskeletal system various trigger points as well as the associated lymphatic system including lymph nodes plus nerves. 

        The high-power MLS® beam has deep tissue penetration of 3-4 cm for optimum treatment outcomes and physiologic results able to reach bone, underlying soft tissues, nerves, sinuses, tendons and muscles attachments. The MLS® laser handpiece contains a high efficiency optical group that provides a more homogenous laser target beam than other devices. This ensures photoreceptors in target cells are activated simultaneously and receive the optimal desired dose.

    • What is the evidence?

      The design of each ASAlaser comes from extensive research in vitro and in vivo.

      Created as a collaboration of ASAlaser and the Biomedical Experimental and Clinical Science Department of Florence University Italy, the ASAcampus laboratory tests the validity of designs and improves results over time.

      The campus undertakes extensive study into the photochemical, photothermal, and photomechanical effects of lasers on biologic tissue including at the molecular level to evaluate therapeutic effects. The results of research are presented at conventions and appear in scientific publications.

      Since 1983 ASAlaser has been a reference point in Laser Therapy and Magnetotherapy in many fields from physiotherapy to rehabilitation, management of muscular and articular pain to sports medicine. The company is a recognised world leader in the knowledge and development of advanced technological development in pain management.

    • We use the MLS® laser in our surgery for our craniofacial pain patients, for patients post-surgery, and we use it quite extensively in orthodontic treatment… This is a device with enormous amounts of clinical research to support its use… it’s a crucial part of what I use in my practice every day in the treatment of patients.
