Dual-path holmium laser

Abstract

The invention discloses a dual-path holmium laser which comprises an outer frame, a laser body, a sealed resonant cavity, a coupling cavity, an improved optical adjusting rack, resonant cavities, a screw rod, a connecting plate, and connecting rods. The screw rod is provided with two sections of threads which are screwed in opposite directions. Two thread sleeves are arranged on the screw rod. Oneend of each connecting rod away from the connecting plate is hinged to the nearby thread sleeve. The improved optical adjusting rack includes a center spacer, an adjusting plate, a first through hole, second through holes, third through holes, planar lenses, threaded columns, inner screw holes, steel balls, and arc slots. As the two resonant cavities in the original sealed resonant cavity are changed from a fixed structure to an adjustable structure, the resonant cavities can be quickly adjusted and restored in the later stage even if the resonant cavities vibrate. Compared with the prior artin which the sealed resonant cavity needs to be dissembled in order to maintain resonant cavities, the maintenance of the resonant cavities in the invention is simpler and more convenient. The redesigned improved optical adjusting rack is more in line with the improved sealed resonant cavity, and the improvement is reasonable.

Description

technical field [0001] The invention relates to the field of resonant cavity structures of laser devices, in particular to a dual-path holmium laser. Background technique [0002] Holmium laser is a pulsed laser made of Cr, Tm, Ho:YAG crystal, its output wavelength is 2.1m in the absorption peak of water, therefore, this laser has a shallow penetration depth to human tissue and has high surgical accuracy. And it is safe for human eyes, and it can be transmitted by optical fiber, so it is a very good light source for surgery in medicine. Therefore, holmium laser has been widely used in the fields of urology, dermatology, obstetrics and gynecology, gastroenterology, general surgery and ENT. [0003] The holmium laser has a high luminous threshold, and the thermal conductivity of the holmium laser crystal is low, so the electro-optical conversion efficiency and output power of the holmium laser are low. In order to obtain a holmium laser treatment machine with high output pow...

Problems solved by technology

[0004] In the existing dual-channel holmium laser, the sealed resonator used to install the laser is often fixed, and each individual resonator is not adjustable, and the laser is a precision instrument, which will be adjusted during transportation and use. , if the laser is cheap, it will not be able to continue to be used, the laser needs to be recalibrated, and sometimes it is even necessary to open the sealed resonator to calibrate a separate resonator, which is very troublesome, and If the resonant cavity is set to be adjustable, the optical adjustment mount used together with the resonant cavity cannot use the traditional structure and needs to be redesigned
