Abstract
A radiation pumped heater includes a ceramic substrate which is heated by a laser beam to a steady state temperature. An optical fiber is heated by conduction and radiation emitted from the ceramic substrate.
Claims10
A method for processing an optical fiber comprising:
- heating a portion of an optical fiber with a radiation pumped heater, the heater comprising a ceramic substrate which is heated by a laser beam to a steady state temperature, and wherein said optical fiber is heated by conduction and radiation emitted from the ceramic substrate;
- drawing the optical fiber to reduce a diameter of the heated portion;
- holding said optical fiber with a proximal holder and a distal holder located on opposite sides of the heated portion, and moving said proximal and distal holders to draw the heated portion of said fiber to the reduced diameter, and wherein said proximal holder is moved at a different velocity than said distal holder at some stage in the method.
A method for processing an optical fiber comprising:
- heating a portion of an optical fiber with a radiation pumped heater, the heater comprising a ceramic substrate, and wherein said optical fiber is heated by conduction and radiation emitted from the ceramic substrate;
- and
- drawing the optical fiber to reduce a diameter of the heated portion;
- wherein said ceramic substrate is heated by a pair of laser beams on opposite sides of said optical fiber to a steady state temperature.
