Abstract

The invention provides a novel holmium laser comprises a total reflective mirror, a light-gathering cavity and a semi-reflective mirror. The light-gathering cavity comprises a housing, a diffuse reflection body, a holmium laser crystal rod and a pulse xenon lamp. End surfaces on two ends of the holmium laser crystal rod are concave. The semi-reflective mirror is in a meniscus shape, and the surface close to the light-gathering cavity is a concave surface. Holmium laser spots emitted from a resonant cavity formed by the total reflective mirror, the holmium laser crystal rod and the semi-reflective mirror is relatively small in divergence angle and more circular in laser spot cross section, so that the focused laser spots are smaller and can be focused into a thinner optical fiber.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a novel holmium laser. Background technique [0002] The wavelength of the holmium laser is 2100nm, which is produced by Cr, Tm, Ho:YAG laser crystals pumped by a xenon lamp. Since the wavelength of the holmium laser is just on the absorption peak of water, its energy can be efficiently absorbed by the water in human tissues, so it is used in medicine It has great application value and is currently mainly used in the fields of stone crushing and tissue cutting. The basic structure of a holmium laser includes a total reflection mirror, a light-condensing cavity, and a half-mirror. The light-gathering cavity includes a holmium laser crystal rod and a pulsed xenon lamp. Among them, a holmium laser crystal rod, a total reflection mirror, and a half-mirror form a resonant cavity. [0003] The full-mirror and half-mirror in the existing holmium lasers all use flat mirrors, so that the...
