A mid-infrared lipolysis laser system was developed with two wave-lengths, 1,980 nm and 2,300 nm. The 1,980-nm and 2,300-nm wave-lengths have high absorption rates for fat and water. The world's first com mercially available lipolysis laser system was developed using these wavelength characteristics. The laser system with a compact design used an 808-nm laser diode and neodymium:yttrium othovanadate crystal that generates a 1,064-nm wavelength with a periodically polarized nonlinear crystal pumping laser beam. A preclinical study was conducted to confirm the safety and efficacy of the lipolysis laser system. A safe and rapid lipolysis laser system was developed as a minimally invasive method.
