ND:YAG LASER FOR REMOVING FATTY TISSUE
First Claim
1. A Nd:
- YAG (Neodymium;
Yttrimium Aluminum Garnet) laser at a wavelength of 1444 nm that directly irradiates laser light onto fatty tissue to remove the fatty tissue and includes a flash lamp for being supplied with a power from a power supply unit and emitting light, a Nd;
YAG rod for amplifying and oscillating the excited laser light inputted from the flash lamp, a high reflection mirror and an output coupler, positioned on both sides of the Nd;
YAG rod, for reflecting the light outputted from the Nd;
YAG rod, the Nd;
YAG laser comprising;
a convergent lens for converging the laser light beam oscillating through the output coupler;
an optical fiber for guiding the laser beam converged by the convergent lens; and
a guide needle, made of metallic material and connected to an end of the optical fiber, for guiding the laser beam from the guide fiber to subcutaneous fat;
wherein both end surfaces of the Nd;
YAG rod, an inner surface of the high reflection mirror, and inner and outer surfaces of the output coupler are coated so as to oscillate only the laser beam at the wavelength of 1444 nm through the output coupler.

Abstract
A Nd:YAG laser at a wavelength of 1444 nm for removing fatty tissue is disclosed, which can directly irradiate laser light onto subcutaneous fat and efficiently remove fatty tissue with an adverse reaction on surrounding tissue minimized by using laser light at an oscillating wavelength of 1444 nm which has both a high fat absorptivity and a high water absorptivity among wavelengths that can be oscillated by the Nd:YAG laser. The Nd:YAG laser includes a flash lamp, a Nd:YAG rod, a high reflection mirror, an output coupler, a convergent lens for converging the laser light beam oscillating through the output coupler, an optical fiber for guiding the converged laser beam, and a guide needle for guiding the laser beam from the guide fiber to subcutaneous fat. Both end surfaces of the Nd:YAG rod, an inner surface of the high reflection mirror, and inner and outer surfaces of the output coupler are coated so as to oscillate only the laser beam at the wavelength of 1444 nm through the output coupler.
