Abstract
The invention relates to a method for producing an infrared transmitting fiber (50) comprising the steps of providing a preform (20) of the infrared transmitting fiber (50) to be produced, said preform (20) comprising a receptacle, which is the precursor of the fiber's cladding, and a solid solution provided inside said receptacle, said solid solution being the precursor of the fiber's core; heating the fiber's preform (20) up to a temperature in which the receptacle softens and the solid solution melts; collecting the flow generated by the softened receptacle; drawing the fiber (50) from the collected flow.
Claims20
A method for producing an infrared transmitting fiber comprising the steps of:
- A) Providing a preform of an infrared transmitting fiber to be produced, said preform having a receptacle which is the precursor of the cladding of the infrared transmitting fiber to be produced, and a solid solution provided inside said receptacle, said solid solution being the precursor of the core of the infrared transmitting fiber to be produced;
- B) Heating the preform of the infrared transmitting fiber to be produced up to a temperature at which the receptacle softens and the solid solution melts, thereby creating a softened receptacle which generates a flow;
- C) Collecting the flow generated by the softened receptacle;
- D) Drawing the infrared transmitting fiber from the collected flow.
A system for producing an infrared transmitting fiber from a preform which comprises a receptacle, said receptacle being the precursor of the infrared transmitting fiber cladding, and a solid solution provided inside said receptacle, said solid solution being the precursor of the infrared transmitting fiber core, wherein the system comprises means for providing the preform;
- means for heating the preform and generating a flow;
- means for collecting the flow generated by the heated preform;
- and means for drawing the infrared transmitting fiber from the collected flow.
A method for treating an infrared transmitting fiber comprising the steps of:
- K) Providing the infrared transmitting fiber to be treated;
- L) Heating the provided infrared transmitting fiber up to a temperature at which its electric dipoles are free;
- M) Applying an electrostatic field to the heated infrared transmitting fiber for moving the electric dipoles towards the direction of the applied electrostatic field.
