Implementation and Demonstration of LUCS, a Live, Ultra-Compact Multispectral USPL Characterization System

Researchers developing Ultra-Short-Pulse-Lasers (USPLs) need real-time measurements of key parameters, on both single-shot and statistical basis. Based on the Phase I results, we propose to assemble and demonstrate a fully integrated, intuitive and user friendly, Live USPL Characterization System, termed LUCS, using novel methods of data capture, data reduction, and distributed processing. Phase II work will integrate the individual diagnostics selected in Phase I into a compact man-portable system designed for the near and short-wave infrared bands of 600-1700-nm, with a 3-5-µm band system developed in the option. In addition, the single shot phase characterization technique will be realized in an extremely compact geometry, which will be insensitive to both alignment and beam profile, simultaneously providing detailed temporal and phase profiles. Advanced data reduction algorithms and system architectures will be implemented and a single graphical user interface (GUI) will display user selectable, processed, laser parameters including live tracking of statistical variations in figures-of-merit. Additionally, the GUI will provide control of all diagnostic system components. The GUI will initially run on a laptop and will ultimately be available as a tablet or smartphone app. The diagnostic subsystems will be seamlessly integrated to provide rapid data processing, with display updates exceeding 10-Hz.
