Sphere Ultrafast Photonics offers world-class products and services for both industrial and scientific applications



The d-scan single cycle is the system of choice for fast and accurate measurement of even the most demanding ultrafast pulses, down to ultra- broadband spectra and single-cycle durations - the shortest for any commercially available device. Its versatile and standalone architecture handles a variety of state-of-the-art ultrashort pulse sources, from broadband laser oscillators, amplifiers and OPAs to hollow-core fiber compressors. The d-scan single cycle’s compact footprint packs a dispersion-calibrated system that measures your pulses exactly as they are, without any ambiguities. Coupling your beam into the d-scan is easily achieved in less than one minute and a full measurement takes less than 10 seconds. The intuitiveness of the d-scan trace provides instant visual feedback for optimisation and control of your source via d-scan’s unique graphical user interface - the Virtual LogbookTM - and the proprietary d-scan algorithm provides fast and accurate retrieval of the complete temporal profile of the pulses.
