System, device and method for stabilizing the optical output power of an optical system

摘要

A light source system for delivery of light including a light source having an output arranged to emit light in an output path, the output path including an unguided section and an at least partially transmissive optical component wherein the optical component provides at least one residual reflection when the system is in use and a detector system is arranged to detect said residual reflection. The detector is in one embodiment arranged to produce at least one feedback response arranged to stabilize the optical output of the light source system. Hereby a feedback may be implemented with little or no reduction of performance.

1. A light source system for delivery of light comprising:
a supercontinuum light source having an output arranged to emit light with a bandwidth spanning over at least one octave with at least 50 μW/nm in an output path, said output path comprising an unguided section and a partially transmissive optical component, wherein said optical component provides a residual reflection of said entire bandwidth of the light when the system is in use, wherein the residual reflection has a substantially same spectral shape as a spectral shape of the output path, and a detector system is arranged to detect said residual reflection via a tap path arranged to collect at least part of said residual reflection wherein said detector system being arranged to produce at least one feedback response arranged to affect light delivered by said system.
