Abstract
A system of delivering power by light, through a fiber. A system for remote operation of an instrument includes a fiber-coupled power laser source, which has an output fiber with a first core diameter. A fiber taper having a wide end and a narrow end, is used to connect the fiber-coupled power laser source to a system fiber having a second core diameter less than the first core diameter. The system fiber delivers optical power to the remote module, in which a fiber-coupled photovoltaic assembly having an input fiber connected to the system fiber, converts the received light to electrical power. The photovoltaic assembly has a first electrical output and a second electrical output, and the photovoltaic assembly is configured to supply power at a first voltage at the first electrical output, and to supply power at a second voltage at the second electrical output.
