Industry 4.0 is a new stage in the organisation and control of the industrial value chain,
interchangeably with the fourth industrial revolution. It has a broad vision with well-defined …

The large-aperture pulse compression grating (PCG) is a critical component in generating
an ultra-high-intensity, ultra-short-pulse laser; however, the size of the PCG manufactured by …

Diffraction efficiency for transmission gratings with period-to-wavelength ratios smaller than
0.6 eg for laser pulse compression is mainly limited due to reflection losses from imperfect …

An all-solid-state single-frequency continuous-wave (CW) 355 nm ultraviolet (UV) laser
based on a dispersion-compensated doubly resonant resonator is presented in this Letter …

The stray light of gratings lowers the image contrast of augmented reality display devices
based on lightguide gratings. We propose to reduce the stray light of gratings fabricated with …

We present a new technique to prevent the detrimental period chirp that appears in optical
gratings fabricated by laser interference lithography (LIL). The idea is to bend the Lloyd's …

In this paper, a doubled-period grating (DPG) method is proposed to measure the scan
angle error in scanning beam interference lithography (SBIL), together with a high-resolution …

Gratings with low diffracted wavefront errors are crucial in many applications. Existing
methods to reduce the diffracted wavefront errors of holographically produced gratings …

We present a theoretical investigation on laser interference lithography used for the
exposure of linear gratings. The focus is on the geometry of the arising interference lines on …

Scanning beam interference lithography (SBIL) is an advanced technology developed for
manufacturing large-area diffraction grating at a nanometer-scale phase accuracy. To …
