Abstract:
Techniques are disclosed for monitoring parameters in a high power fiber laser or amplifier system without adding a tap coupler or increasing fiber length. In some embodiments, a cladding stripper is used to draw off a small percentage of light propagating in the cladding to an integrated signal parameter monitor. Parameters at one or more specific wavelengths (e.g., pump signal wavelength, signal/core signal wavelength, etc) can be monitored. In some such cases, filters can be used to allow for selective passing of signal wavelength to be monitored to a corresponding parameter monitor. The filters can be external or may be integrated into a parameter monitor package that includes cladding stripper with integrated parameter monitor. Other parameters of interest (e.g., phase, wavelength) can also be monitored, in addition to, or as an alternative to power. Numerous configurations and variations will be apparent in light of this disclosure (e.g., system-on-chip).
