Abstract
A laser apparatus for selective photocoagulation of subsurface skin (dermis) for the purpose of increasing skin tone, reducing wrinkles, removing hair, removing tattoos or treating varicose veins without damaging the skin surface (epidermis). A diffuser lens in the laser apparatus is employed to focus the laser energy to the dermis. The laser apparatus includes a highly transmissive contact tip and cooling means to reduce heat build-up in the contact tip, as monitored by a thermocouple mechanism. The device can be used alone or in conjunction with superficial laser resurfacing or chemical peels to increase skin tone.
Claims13
A laser apparatus comprising a laser source for delivering laser energy in optical communication with a light transmissive contact tip and optics arranged to defocus the laser energy at the surface of the contact tip and focus the laser energy outside of the contact tip wherein the wavelength of laser energy is between 800 nanometers and 1.79 microns.
The laser apparatus of claim 5, further comprising a handpiece containing a fiberoptic bundle in optical communication with the laser source and a diffuser lens which focuses the laser in the dermis without damage to the epidermis.
