Background technology
At present; The holmium laser that is mainly used in medical field is generally pulse mode work; Improve constantly in order to adapt in the medical application requirements such as output laser power to laser, single pulse energy, operating frequency; Adopt the two-way holmium laser for this reason, thereby improve power output and pulse energy greatly.But because the laser crystal that holmium laser adopted work under 2～10 ℃ cryogenic conditions usually; Therefore laser works need be taked compressor cycle water refrigeration at ambient temperature; Airborne steam will influence the energy output of laser in the optical element surface dewfall; Especially adopted the two-way holmium laser, just increased the weight of steam in the optical element surface dewfall more, when serious even cause the output of laser noenergy.
Summary of the invention
The purpose of the utility model is to provide a kind of sealing two-way holmium laser that can effectively avoid airborne steam in optical element surface dewfall, the normal output of assurance twin-channel laser energy.Have compact conformation, effect significantly, easy mounting, convenient, the steady operation and other merits of debugging.
A kind of sealing two-way holmium laser that the utility model provided comprises resonance annular seal space, resonant cavity A, resonant cavity B, coupling cavity, 45 ° of reflecting optics adjusting brackets, revolving mirror adjusting bracket, five times regualting frame, fiber optic hubs and the median septum that between resonance annular seal space and coupling cavity, is provided with.Wherein said resonance annular seal space is made up of resonant cavity A resonant cavity B, and resonant cavity A is made up of A road holmium laser cavity, A road back cavity sheet adjusting bracket, A road ante-chamber sheet adjusting bracket; Resonant cavity B is made up of B road holmium laser cavity, B road back cavity sheet adjusting bracket, B road ante-chamber sheet adjusting bracket.Said coupling cavity is to be made up of 45 ° of reflecting optics adjusting brackets, revolving mirror adjusting bracket, five times regualting frame, fiber optic hub.Said on the median septum that is provided with between resonance annular seal space and the coupling cavity, as to be embedded with resonant cavity A corresponding position level crossing A, successively with coupling cavity in revolving mirror adjusting bracket, five times regualting frame, fiber optic hub parallel; The level crossing B that is embedded with resonant cavity B corresponding position regulates with 45 ° of reflecting optics in the coupling cavity and to put up 45 ° of angles, and 45 ° of reflecting optics adjusting brackets is put up 45 ° of angles with the revolving mirror adjusting.
Because the median septum that is provided with between resonance annular seal space and the coupling cavity; Secluding air gets into the resonance annular seal space; Make the resonant cavity A resonant cavity B that places two-way holmium laser cavity be able to sealing; Thereby avoid airborne steam to occur, guarantee that the energy of twin-channel laser is normally exported in the situation of optical element surface dewfall; Said on the median septum that is provided with between resonance annular seal space and the coupling cavity, with the level crossing A that resonant cavity A corresponding position is embedded with, the laser that resonant cavity A is sent sees through level crossing A and gets into coupling cavity, is close to revolving mirror adjusting bracket edge and injects in the five times regualting frame; The level crossing B that is embedded with resonant cavity B corresponding position; The laser that resonant cavity B is sent; See through level crossing B and get into coupling cavity, to the revolving mirror adjusting bracket, reflection gets in the five times regualting frame again through 45 ° of reflecting optics adjusting bracket back reflections; Two-way laser has significantly improved power output and pulse energy through converging to fiber optic hub output behind the five times regualting frame.Have compact conformation, effect significantly, easy mounting, convenient, the steady operation and other merits of debugging.
