A kind of discharging structure of laser

[technical field]

The utility model relates to a kind of laser, relates in particular to a kind of discharging structure of laser.

[technical background]

In existing high power laser discharging structure, because resonant cavity (discharge tube inside) is difficult to avoid impurity to enter in assembling process, and in the resonant cavity course of work, owing to produce high temperature, some adjuncts that are attached to inwall can form carbide, become some tiny black patchess, thereby pollute the gas that flows in the resonant cavity, cause the instability of gas flow, thereby influence the stability of light path.Discharge tube of the prior art as shown in Figure 1, the sidewall of discharge tube has an opening, be used for being connected of anode and discharge tube, if intra resonant cavity is cleaned, must all disassemble whole resonant cavity just and can finish, workload be very big, and finishes when reinstalling in cleaning, also will carry out the mode adjustment of resonant cavity, very trouble works together.So the defective that exists in the prior art is: operational environment is vulnerable to pollute in the resonant cavity, can't clean immediately, influences the stability of light path.

[utility model content]

The technical problem that the utility model institute desire solves provides a kind of discharging structure of laser, under the prerequisite of not dismantling resonant cavity, can keep resonant cavity operational environment cleaning, thereby purify light path.

The technical scheme that the utility model adopted is:

A kind of discharging structure of laser, comprise discharge tube and anode, described discharge tube comprises the discharge tube body, on the close sidewall of discharge tube body one end, have the discharge mouth, the position of the position of described anode and described discharge mouth is corresponding, also comprise dust arrester, described discharge tube also comprises dust arrester mount pad mouth, on the sidewall relative, dust arrester mount pad mouth is set with described discharge mouth, described dust arrester is fixed on the described dust arrester mount pad mouth, and is communicated with the discharge tube body by described dust arrester mount pad mouth.

The discharging structure of described a kind of laser also comprises silicone tube and sealing ring, and described sealing ring is arranged between dust arrester and the dust arrester mount pad mouth, and described silicone tube is socketed on dust arrester and the dust arrester mount pad mouth.

The discharging structure of described a kind of laser also comprises O-ring seals, and described discharge tube also comprises anode mount pad mouth, and described anode mount pad mouth is arranged at described discharge mouthful place, and described anode is seal-installed in the anode mount pad mouth by described O-ring seals.

The built-in length of described anode in anode mount pad mouth do not exceed described discharge tube inner body wall, or consistent with described discharge tube inner body wall.

Described anode comprises anode pin, anode needle stand and anode ring, and described anode pin is fixed on the anode needle stand, and described anode ring is arranged on the anode needle stand, and forms the space that holds described anode pin with described anode needle stand.

Described dust arrester is a bend pipe.

The beneficial effects of the utility model are:

Owing on sidewall relative on the discharge tube body, be provided for installing the dust arrester mount pad mouth of dust arrester with the discharge mouth, in the resonant cavity course of work, the discharge of anode one end, air-flow enters dust arrester under the effect of instantaneous power, and fine impurities can rest in the dust arrester, thereby plays the effect that purifies the resonant cavity operational environment.Under the laser stopped status, can unload dust arrester and clear up, reinstall after cleaning up, easy to operate, the resonant cavity operational environment is kept clean constantly, be beneficial to the generation of light path; Also be provided with the anode mount pad mouth that is used to install anode near the discharge mouth place on the discharge tube body, be convenient to can guarantee the position when anode is installed, and favorable sealing property.
