We present a progress review on the advance of distance measurements made at KAIST by
making use of mode-locked lasers as the light source to meet ever-growing industrial …

Laser-based light detection and ranging (lidar) plays a significant role in both scientific and
industrial areas. However, it is difficult for existing lidars to achieve high speed, high …

We demonstrate dual-comb time-of-flight absolute distance measurement with a free-
running dual-wavelength dual-comb mode-locked Er-fiber laser. An anodized aluminum …

We present an absolute distance measurement system using a phase-stable dual-comb
system with 56.09 MHz repetition rate and 2 kHz repetition rate difference. A relative phase …

Long-distance ranging is a crucial tool for both industrial and scientific applications. Laser-
based distance metrology offers unprecedented precision making it the ideal approach for …

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 …

A new absolute distance measurement system is demonstrated in this paper, which is based
on a dual-wavelength passive mode-locked fiber laser. By controlling the intracavity loss …

Ultrashort pulse lasers are emerging as an advanced tool of distance measurement, with
their unique temporal and spectral characteristics being extended to diverse principles of …

Dual-comb spectroscopy provides a marked advantage over single-comb techniques for
molecular fingerprinting, particularly in terms of scanning speed. The single-cavity dual …
