State of the Art Laser Therapy


Research studies, along with an understanding of the hazards of sunlight and conventional, man-made light sources have permitted scientists to establish safe exposure limits for nearly all types of laser radiation. These limits are generally referred to as Maximum Permissible Exposures (MPE's) by laser safety professionals. In many cases it is unnecessary to make use of MPE's directly. The experience gained through millions of hours of laser use in the laboratory and industry has permitted the development of a system of laser hazard categories or classifications. The manufacturer of lasers and laser products is required to certify that the laser is designated as one of four general classes, or risk categories, and label it accordingly. This allows the use of standardized safety measures to reduce or eliminate accidents depending on the class of the laser or laser system being used.

Each of Erchonia Medicalís Laser products are designed to comply to the highest standard of Laser Safety. It is our goal to ensure that the end user of all of our products has a complete understanding on the classification and the correct use of their newly purchased Laser. Since all of Erchonia Medicalís Laser Products are low power, visible, and nonionizing they fall within the FDA classification of Class 3A and Class 3B. The 3A line of Laser Products at Erchonia (which operate at 5mw or under) are: The PL5, PL3, EVRL,THL-1,the BST 3A, and the BST Violet . The 3B line of Laser Products at Erchonia (which operate at 50mw and under) are the; EML, the BST 3B, and the Laser Scanner. Before we take a look at those classifications let us review the following:

What is a Laser?

LASER is an acronym which stands for Light Amplification by Stimulated Emission of Radiation. The energy generated by the laser is in or near the optical portion of the electromagnetic spectrum (see Figure 1). Energy is amplified to extremely high intensity by an atomic process called stimulated emission. The term "radiation" is often misinterpreted because the term is also used to describe radioactive materials or ionizing radiation. The use of the word in this context, however, refers to an energy transfer. Energy moves from one location to another by conduction, convection, and radiation. The color of laser light is normally expressed in terms of the laser's wavelength. The most common unit used in expressing a laser's wavelength is a nanometer (nm). There are one billion nanometers in one meter.

The optical spectrum. Laser light is nonionizing and ranges from the
ultra-violet (100 - 400nm), visible (400 - 700nm), and infrared (700nm - 1mm).
