Chromatic confocal technology is widely used for precise, steady, and efficient displacement
measurement in many industrial fields. It employs the confocal and dispersion principles to …

An all-fiber single-short-cavity dual-comb laser with a high repetition rate of up to 500 MHz
and a high repetition rate difference of over 120 kHz was demonstrated. The laser setup …

Dual-comb spectroscopy (DCS) has been an emerging spectrometric technique with high
resolution, high sensitivity, broad spectral range and fast acquisition speed. However, it is …

An ultra-high birefringent D-shaped microfiber device with birefringence over 4× 10− 2 and
insertion loss down to 0.2 dB is proposed and experimentally demonstrated. When the all …

In this Letter, we report a scheme that combines time-of-flight (ToF) ranging detection of multi-
repetition-rate pulses with asymmetric dual-comb ranging (DCR) measurement. Notably, this …

Dual-comb ranging (DCR) is an important method in absolute distance ranging because of
its high precision, fast acquisition rate, and large measuring range. DCR needs to obtain …

We show that by breaking the symmetry of a beam subjected to tight focusing, namely by
obscuring half of it or, equivalently, shifting the beam away from the lens axis, it is possible to …

Asynchronous dual-comb generated in single laser cavity offer potent tools for simplified
coherent measurements, owing to the common mode rejection which spares the …

Dual-comb ranging (DCR) is an emerging absolute distance measurement method with
rapid speed, high precision, and wide ambiguity range. DCR has important applications in …

Dual combs are widely recognized for their significant applications in precision
measurement, due to their high spectral resolution, broad spectral range and high speed …
