Abstract:
     Being in use for machine tool of fabricating preformrod of PCVD optical fiber, the tunable resonant cavity of plasma includes columned body case of resonant cavity. Cut off waveguide is setup at two ends of the columned body case of resonant cavity. Characters are that tuning screw pin is setup at one end of the columned body case of resonant cavity. Adjusting insertion depth of the tuning screw pin at any moment can reach tuning effect to make waveguide device match to load of resonant cavity well in order to adapt to everchanging equivalent load of resonant cavity in course of working so as to realize real time control of energy coupling. The invention helps to increase working accuracy and efficiency of PCVD technique, and prevent damage on system device from microwave so as to raise useful service life of system. Features are: simple structure, stable performance, convenient for fabrication.
