title: Fiber-array-based detection scheme for single-shot pulse contrast characterization.
abstract: We propose and demonstrate a fiber-array-based detection scheme for single-shot pulse contrast characterization. The parallel to serial mapping using the fiber array allows the use of a high-sensitivity photomultiplier tube and eliminates the external neutral density filter, both resulting in significantly improved dynamic range. The proof-of-principle experiments show a dynamic range of 2x10(7):1. The demonstrated technique can be readily applied to existing instruments for single-shot pulse characterization.
