Abstract
An optical waveguide pumping method can include pumping a liquid fluid through a conduit, thereby pumping an optical waveguide into the conduit, and operating a fluid recovery device, so that fluid pressure in the conduit is less than a vapor pressure of the fluid and/or fluid temperature in the conduit is reduced from above a boiling point temperature of the fluid to below the boiling point temperature of the fluid. An optical waveguide pumping system can include a pump which pumps a liquid fluid into a conduit and thereby pumps an optical waveguide into the conduit, and a fluid recovery device connected to the conduit. The fluid recovery device reduces fluid pressure in the conduit to below a vapor pressure of the fluid and/or reduces fluid temperature in the conduit from above a boiling point temperature of the fluid to below the boiling point temperature of the fluid.
