Abstract
An insight is given into the fundamental mathematics and physics behind the generation of ultrashort optical pulses by mode-locked lasers, followed by an analysis and comparison of the characteristics between different types of such lasers, from the point of view of applications in dimensional metrology. Measurement technologies utilizing ultrashort pulses as time ruler and nonlinear optics generator in time domain, frequency ruler and white light laser in frequency domain, as well as applications in standards and traceability, are then categorized and presented. Future challenges and developing trends are also discussed.
