Deep Tissue Low Intensity Laser Therapy or Treatment (DT-LILT) as described here is a novel methodology through which selective destruction of nociceptive (pain) nerves can be brought upon by a medical laser delivery system using the phenomenon of absorption and cell resonance. Using this method nerve cells that transmit pain can be selectively destroyed leaving the surrounding tissues intact as no heat is generated. The delivery system incorporates a fine needle through which a 703 nm (range 690 to 710) pulsed wave low intensity laser is delivered deep into the body, directly to the area of pain causing selective destruction of pain nerves. Laser devices based on this methodology should be used only by the physician or equivalent professional community since diagnosing and defining the area of pain is critical to providing successful pain relief.

A method of manufacturing a workpiece involves performing any one of various post-processing part modification steps on a workpiece that has been previously subjected to laser shock processing. In one step, material is removed from the compressive residual stress region of the processed workpiece. Alternately, the workpiece may be provided with oversized dimensions such that the removal process removes an amount of material sufficient to generate a processed workpiece having dimensions substantially conforming to design specifications. Alternately, the material removal process is adapted to establish a penetration depth for material removal that coincides with the depth at which the workpiece exhibits maximum compressive residual stress. Alternately, a first high-intensity laser shock processing treatment is performed on the workpiece, followed by the removal of material from the compressive residual stress region, and then a second low-intensity laser shock processing treatment is performed on the workpiece. Material may be removed from the compressive residual stress region through a workpiece surface different from the laser shock processed surface. Material may also be deposited onto the laser shock processed surface.

A portable, small-footprint laser device contains one or more housings in which a laser energy source and an optical arrangement are disposed. The housing produces a laser beam spot that may be rotated and scanned to apply laser energy to a target area. The laser device receives treatment parameters and uses them to program a treatment regimen in which activation and movement of the housings is automated. The laser device may be used to apply a treatment regimen to a patient's hands or feet that are infected by Onychomycosis. In the treatment regimen, certain wavelengths of laser energy are applied at a predetermined duration. The treatment may be repeated, and a topical anti-fungal medication may be applied to aid in the efficacy of the treatment.

Methods for treating fungal infections of the hand or foot use applications of low level laser energy to the infected area to inhibit fungal growth. A laser device is used to produce one or more low-level laser beams, typically in the range of 400-800 nm emanated at a power of less than 1 watt. The laser light is scanned across the infected area for a predetermined duration. Preferably, the duration is between about 10 and 30 minutes, so that at least 0.5 joules of laser energy is applied. Preferably, about 10 joules of laser energy is applied. The application may be repeated, and is preferably repeated once, about five weeks after the first application. A topical medication, such as an antifungal cream, may be used in conjunction with the laser light to speed up fungal removal.

The invention relates to a polarized light scattering measurement system and method based on magneto-optic modulation. Coherent light sent out by a laser is changed to linear polarized light through a polarizer, and the linear polarized light is focused into a sample matching tank through a focusing lens.
