Multipath pulse laser integrated system

Abstract

The invention relates to a multipath pulse laser integrated system on a quasi-molecule laser ophthalmic therapy apparatus, realizing the light path synthesis of at least two laser beams through a mechanical mode. A porous rotary wheel (or porous reflecting mirror) is arranged in the multipath pulse laser integrated system, a small hole and the reflecting mirror are alternated by utilizing the rotation of the rotary wheel through a mechanical shutter mode. A light-emitting diode is arranged in front of the rotary wheel, a photoelectric detector is placed behind the rotary wheel, the permeation of the light rays of the light-emitting diode is controlled through the rotation of the rotary wheel, the photoelectric detector can generate voltage timing-sequence signals to control the starting of different lasers, thereby achieving the integration of laser pulses. The multipath pulse laser integrated system ensures that a laser source of the quasi-molecule laser ophthalmic therapy apparatus simultaneously satisfies the requirements of high-pulse frequency, high-energy stability and sufficient pulse energy, and provides a technical solution scheme for the clinical application of the quasi-molecule laser ophthalmic therapy apparatus at present.

Description

technical field [0001] The invention relates to a multi-channel pulsed laser integrated system, especially a multi-channel pulsed laser integrated system used in a laser corneal refractive surgery system, which realizes optical path multiplexing of two or more laser beams to obtain high pulse frequency , high energy stability and sufficient pulse energy laser. Background technique [0002] Excimer laser therapy accounts for most of the current market for refractive surgery. As the core part of excimer laser therapy equipment, laser light source has high technical requirements, and the quality of laser light source will directly affect the effect of surgery. In order to meet the requirements of excimer laser ophthalmology treatment, the laser light source used must meet the three requirements of high pulse frequency, high energy stability and sufficient pulse energy. For an excimer laser, the higher the pulse energy, the more expensive it is; and when the laser works at a h...
