Trapping and manipulating micro-size particles using optical tweezers has contributed to many breakthroughs in biology, materials science, and colloidal physics. However, it rem...
A noise-like pulse (NLP) is generated in an anomalous-dispersion passively mode-locked erbium-doped fiber laser using graded-index multimode fiber (GIMF) as the all-fiber satura...
Ultrafast lasers have emerged as a versatile tool for fabricating optical waveguide devices inside transparent materials. Recent works show that they are subject to scientific s...
Black ice is a thin coating of ice on a surface, notably on a road surface, as shown in Fig. 1. Black ice is not black but visually transparent, allowing the road below to be se...
We describe an improved synthetic wavelength method for high-precision long-distance measurement with a repetition-rate-locked femtosecond laser modulated by a fiber Mach–Zehnd...
On-orbit measurement of middle and upper atmospheric wind field provides critical data for several applications such as space society, global communication, weather forecasting....
