Abstract

The invention is applicable to the field of optics, and provides a laser output device and a laser ablation system. The laser output device comprises a laser and a coupling module which are connected in sequence; the laser is used for generating an initial light beam emitted to the coupling module, and the initial light beam is a light beam conforming to Gaussian energy distribution; the coupling module comprises a laser beam shrinking module, a homogenizing module and a focusing coupling module which are connected in sequence, and is used for converting the initial light beam into a target light beam and coupling the target light beam to the guide pipe, and the target light beam is a light beam with uniform energy distribution. According to the embodiment of the invention, the energy of the laser beams reaching the catheter can be homogenized, the spatial coherence of the beams is reduced, the situation that the energy of the laser is transversely redistributed to burn out the catheter is avoided, the energy loss of the output laser is also reduced, and the energy conversion rate of the laser is improved, so that the plaque ablation speed of laser ablation is increased.

Description

technical field [0001] The application belongs to the field of optics, and in particular relates to a laser output device and a laser ablation system. Background technique [0002] People with high blood pressure, high blood fat, heavy smoking, diabetes, and obesity are prone to atherosclerosis. Atherosclerosis can cause stenosis or blockage of the blood vessel lumen, resulting in no blood flow, which is life-threatening. [0003] Arterial interventional therapy has become an effective means of treatment for patients with atherosclerosis. Arterial interventional therapy uses laser ablation and other means to dredge narrowed or blocked blood vessels by delivering device catheters into blood vessels. [0004] Laser ablation technology refers to a medical technology that uses ultraviolet laser to irradiate atherosclerotic plaque in blood vessels to ablate it. After ultraviolet rays are absorbed by atherosclerotic plaques, they can destroy the carbon-hydrogen bonds of plaque ...
