d-max
The Ultimate Measurement Tool for Ultrafast Laser Systems and Hollow-Fiber Compressors
The d-max is the preferred system for quickly and accurately measuring even the most challenging ultrafast pulses, including ultra-broadband spectra and few-cycle durations. Its compact, standalone design supports a variety of ultrashort pulse sources, such as broadband laser oscillators, amplifiers, OPAs, and hollow-core fiber and multipass cell post-compressors.
The d-max’s compact design packs a dispersion-calibrated system that measures your pulses exactly as they are, without ambiguity. Beam coupling is easy and a full measurement is completed in under 10 seconds. The intuitive d-max trace provides instant visual feedback via the unique Virtual Logbook™ interface, and its proprietary algorithm ensures fast, accurate pulse reconstruction.
