摘要：
A laser system including: a laser source operable to emit a first and a second laser beam having first and second operating wavelengths, respectively； a fiber optic cable to guide and homogenize the laser beams； an expander to increase the diameter of the laser beams； a cylinder to guide the laser beams and limit respective diameters of the first and second laser beams, wherein the cylinder is positioned after the expander on an optical path of the laser beam； a first optical system to collimate the laser beams, wherein the optical system is positioned after the cylinder on the optical path of the laser beams； a spot-size selector comprising a plurality of apertures, wherein the spot-size selector is positioned after the first optical system on the optical path of the laser beams； and a second optical system to focus the laser beams on a tissue of the patient.
