Embodiment Construction

[0013] Such as figure 1 As shown, a specific embodiment of a quad-core holmium laser generating system according to the present invention is provided. In the figure, four groups of holmium laser resonators 4 are parallel to each other to form a square, which are respectively located on the four corners of the square , the rear cavity mirror 3 of each holmium laser resonator 4 is a total reflection mirror, the laser light 10 generated by the resonator is reflected by the rear cavity mirror 3 to the output of the front cavity mirror 5, and then reflected by the total reflection mirror 7 to the total reflection mirror 6. After being reflected by the total reflection mirror 8 controlled by the servo motor 9, it is converged by the coupling mirror 2 and then output through the optical fiber 1.

[0014] Since the total reflection mirror 8 can rotate according to the emission sequence of the four groups of holmium laser resonators 4 under the control of the servo motor 9, so the lase...

Abstract

The invention discloses a four-core holmium laser generation system. The system comprises a coupling lens, four groups of holmium laser resonant cavities, total reflection mirrors and a servo motor, and is characterized in that: the four groups of the holmium laser resonant cavities are parallel to each other to form a square and are respectively positioned at the four corners of the square; the total reflection mirrors can rotate according to the transmitting order of the four groups of the holmium laser resonant cavities under the control of the servo motor; and the laser light generated by the holmium laser resonant cavities is output, the laser light is reflected to the coupling lens by the total reflection mirrors controlled by the servo motor and is output through an optical fiber. Each group of the holmium laser resonant cavities is provided with two total reflection mirrors in a group; and the four groups of the holmium laser resonant cavities share a parallel circulating water cooling system for cooling. The four-core holmium laser generation system has a simple structure, is easy to realize and very simple to install and adjust, improves service efficiency and reduces cost.

Description

technical field [0001] The invention relates to the field of laser therapy devices, in particular to a quad-core holmium laser generating system. Background technique [0002] The holmium laser has a wavelength of 2100nm, which is generated by Ho:Cr:Tm:YAG laser crystals pumped by a xenon lamp. It belongs to the mid-infrared range, and its wavelength is close to the first absorption peak of water at 1950nm (biological organisms contain 70%-80% water). Therefore, the holmium laser is easily absorbed by biological tissues quickly, and its effect can be fully exerted, and it has excellent ablation, coagulation, vaporization, and cutting effects. Therefore, the holmium laser is not only suitable for body surface surgery, but also can be used in conjunction with endoscopes and various tools. Currently, it is mainly used for urinary stone crushing and tissue cutting. Since the thermal lens effect is obvious when the Ho:Cr:Tm:YAG laser crystal works at a high repetition rate, the ...
