Optical tweezers have emerged as a powerful and flexible tool for manipulating biological and colloidal particles in a non-contact manner. Compared with standard Gaussian single-beam, the holographic optical tweezers provide a more convenient way to pro...
It is well-known that light can carry both linear momentum and angular momentum (AM) when interacting with a small particle, the optical linear momentum or/and AM can be transferred to the particle, resulting in observable mechanical effects. Unlike vor...
High-power tunable light sources around 1 μm wavelength region is a mature and widely used technology. Such high power, wavelength tunable Yb-doped fiber lasers (YDFLs) light sources are extensively used as excellent pump sources. However, the stochast...
For ultrasensitive sensors, the high Q resonance with extremely narrow bandwidth is important and necessary, which indicates the lower rate of energy losses and supports strong interaction between electromagnetic waves and analytes. However, the metalli...
Phase-contrast imaging has been widely applied in optical and X-ray measurements since the phase contains information about the 3D morphology and refractive index of the specimen. A phase map can be retrieved from a single-distance coherent diffraction imag...
