Title:
MEDICAL LASER WITH COLLABORATIVE OUTPUT OF SOLID-STATE PULSE THULIUM LASER AND GREEN LASER
Document Type and Number:
WIPO Patent Application WO/2022/236953
Kind Code:
A1
Abstract:
A medical laser with collaborative output of solid-state pulse thulium laser and green laser, the medical laser comprising an axially extending housing, wherein a first partition is radially and fixedly connected in the interior of the housing; a second partition, which is fixedly connected to one side surface of the first partition, wherein the interior of the housing is partitioned into a thulium laser generation cavity, a green laser generation cavity, and a light-mixing cavity by the first partition and the second partition; a second total reflection mirror, a thulium rod, an acousto-optic modulator Q and a 5% spectral output mirror, which are coaxially and fixedly mounted in the thulium laser generation cavity; a second 45-degree total reflection mirror, which is used for reflecting a laser into the light-mixing cavity and is fixedly mounted at a laser-emitting end of the thulium laser generation cavity; a first total reflection mirror, a neodymium-doped yttrium aluminum garnet rod, a frequency-doubling crystal and a green laser output mirror, which are coaxially and fixedly mounted in the green laser generation cavity; and a first 45-degree total reflection mirror, which is adjustably connected in the light-mixing cavity, wherein a side wall of the light-mixing cavity is coupled with an optical fiber. The laser generator having the complementary cooperation of the green laser with a wavelength of 532 nm and the thulium laser with a wavelength of 2025 nm meets multi-functional requirements of wrinkle removal, skin erythema removal and surgical lithotripsy in medical cosmetology.
