In this study, femtosecond laser-based multi-beam interference laser processing on nanofilms with nanometer thicknesses was demonstrated. The resulting multi-hole, two-dimensional lattice pattern reflected a laser interference fringe formed on the su

Optical enhancement cavities enabling laser pulses to be coherently stacked in free space are used in several applications to enhance accessible optical power. In this study, we develop an optical cavity that accumulates harmonically mode-locked lase

Increasing the acquisition speed of three-dimensional volumetric images is important—particularly in biological imaging—to unveil the structural dynamics and functionalities of specimens in detail. In conventional laser scanning fluorescence micr

Laser-based Micro- and Nanoprocessing XV.
In this paper, we demonstrated the processing of free-standing thin films by the ultrafast laser ablation, which has been difficult to process using existing nanoprocessing methods such as focused ion beam milling. First, we fabricated a holographic

We present a novel method of optical trapping by a size-controllable dark spot produced by dual vortex beams, which realizes stable manipulation of micrometer size particles with a low refractive index.

The properties of electron round lenses produced by the ponderomotive potential are investigated in geometrical optics. The potential proportional to the intensity distribution of a focused first-order Bessel or Laguerre-Gaussian beam is exploited to

Tight focusing of a radially polarized beam is used for single-shot laser ablation of metals. The strong longitudinal field is generated at the focus, and its contribution to the ablation process is comprehensively examined for various metal material

The creation of ultraviolet optical vortex beams with the topological charge of | l | = 1 at the wavelength of 325 nm was demonstrated from a He–Cd metal vapor laser with a spot defect mirror. The measured M 2 factor was close to the theoretical va
