Laser system for producing infrared radiation of 2100nm for cartilage treatment

摘要

PURPOSE: A laser system of producing infrared rays having wavelength of 2100NM for cartilage or urinary organs treatment is provided to reduce the manufacturing cost by using infrared light source having a wavelength of 2100nm instead of a Ho:YAG laser. CONSTITUTION: An Nd:YAG laser module(13) is used for oscillating light having a wavelength of 1064nm. An AO(Acoustooptic) modulator(12) is used for performing a Q-switching operation for the light of 1064nm. An end mirror(11) is used for resonating the light of 1064nm. A Breswster window(14) and a half-wave plate(15) are used for polarizing lineally the light of 1064nm. An OPO(Optical Parametric Oscillator)(16-19) is used for receiving the linear polarized light of 1064nm as pump beam and outputting light of 2100nm.
