Junction tilts, and resonant cavity tail portion speculum, which synchronizes, to be tilted, and resonant cavity luminous lens resonant cavity tail portion mirror parallel degree is caused
Error increases, and causing beam quality to decline power reduces.
2, discharge tube by two layers of hard glass fires itself there are uneven disorderly stress, by laser pipe shell and flanged pipe
Three binding site, water inlet pipe, outlet pipe fixed points are fixed, since glass internal stress eliminates the period after laser tube body overall processing is good
Very long, three supporting point stress of discharge tube gradually discharge in some months after laser manufacture, the discharge tube stress after 2-3 months
Release causes laser tube tail portion flange port adhesive surface to tilt, and equally causes resonant cavity luminous lens resonant cavity tail portion speculum flat
Row degree error increases, and causing beam quality to decline power reduces.
3, since laser cooling water temperature is different, use environment is different, causes discharge tube heat to increase shrinkage, causes laser tube
Tail portion flange port adhesive surface tilts, and resonant cavity luminous lens resonant cavity tail portion mirror parallel degree error is equally caused to increase,
Causing beam quality to decline power reduces.

Pipe, cooling water flows back into external water source after cooling water pipe from outlet pipe, and then realizes the cycle of cooling water pipe cooling water, makes to put
Fulgurite obtains good cooling.
The utility model is further arranged to：The laser tube enclosure is equipped with supporting rack, support frame as described above and cooling
Water tube surfaces connect.When laser works, cooling water is entered from water inlet pipe in cooling water pipe, from water outlet after cooling water pipe
Pipe flows out, since there are temperature differences between cooling water and water inlet pipe, outlet pipe, after cooling water enters water inlet pipe, due to heat
Swollen shrinkage, cooling water pipe length also can it is corresponding on change, water cooling tube curvature is reduced by supporting rack, it is accurate to improve laser
Degree.
The utility model is further arranged to：The water inlet pipe and outlet pipe are located at laser pipe shell the same side.
The utility model is further arranged to：The discharge tube uses hard glass.With fast response time (ns grades), resistance to
Impact, the advantages that performance is stable, reproducible and long lifespan.
The utility model has the beneficial effect that：
Traditional laser is easily caused laser tube tail portion flange port adhesive surface and tilted, equally caused due to many reasons
Resonant cavity luminous lens resonant cavity tail portion mirror parallel degree error increases, and causing beam quality to decline power reduces.And this
Utility model discharge tube tail portion one end use bellows structure, can utmostly absorb expand with heat and contract with cold and gravity caused by it is micro-
The flexible tilting force of amount ensures that laser tube tail portion flange section is indeformable, keeps resonant cavity luminous lens resonant cavity tail portion speculum long
Period is in best parastate, exports best beam quality and most stable of laser power.
