THE HIGH-PERFORMANCE TOOL FOR MASTERING YOUR HOLLOW-FIBER OR MULTIPASS CELL POST-COMPRESSOR DOWN TO FEW-CYCLE PULSES
The d-max is the system of choice for fast and accurate measurement of even the most demanding ultrafast pulses, down to ultra-broadband spectra and few-cycle durations. Its compact, standalone design supports a wide range of ultrashort pulse sources, including broadband laser oscillators, amplifiers, OPAs, and hollow-core fiber and multipass cell post-compressors. The d-max’s compact footprint packs a dispersion-calibrated system that measures your pulses exactly as they are, without ambiguities. Beam coupling takes less than a minute, and a full measurement completes in under 10 seconds. The intuitive d-max trace gives instant visual feedback via the unique Virtual LogbookTM interface, while its proprietary algorithm ensures fast, accurate pulse reconstruction.
