The nickel‐titanium (NiTi) alloy, “Nitinol”, has become a prominent name in the medical device industry amongst medical device manufacturers. The unique properties of the material, such as the shape memory effect and pseudoelasticity, have earned the material increasing popularity for new product innovations. Amongst the various manufacturing processes for metal alloys, laser micromachining has taken the lead for processing Nitinol‐based products. This literature review provides an analysis of the history and applications of Nitinol, an overview of the microstructure of the material, and a review of the current manufacturing methods for laser cutting medical‐grade Nitinol. A more in‐depth focus is placed on the realm of laser processing and the challenges associated with the manufacturing process. Ultrafast femtosecond pulse processing delivers promising results and quality for manufacturing Nitinol medical devices. However, there exists a need to investigate potential approaches to increase the cutting speed of the process to enhance throughput and stay competitive in a growing market due to the cutting speed being over 4‐times slower than long pulse cutting. Many tactics to address the problem are discussed, ranging from laser selection, processing parameters, and non‐traditional laser processing approaches.This article is protected by copyright.

“…The main restriction preventing the use of plasma-based X-ray lasers for sounding the dynamics of rapid processes is the significant (usually picosecond) duration of the radiated pulses. In recent years, the possibility of reducing the duration of plasma-based X-ray laser radiation to tens (in theory) and hundreds (in experiment) of femtoseconds by increasing the number density of free electrons [17,18] and amplifying the frequency-modulated seeding radiation (one of the harmonics of the high-order optical field) with subsequent compensation for frequency modulation has been shown [19,20].…”

We study the possibility of transforming quasi-monochromatic seeding X-ray radiation into an attosecond pulse train in the system composed of a resonant absorber (the plasma of hydrogen-like ions) and an active medium of a plasma-based X-ray laser (the plasma of identical ions in the excited state), which are modulated by the same optical field. In this case, the formation of pulses occurs in a modulated absorber, while the active medium is used for their subsequent amplification. It is shown that this approach significantly increases the energy of the pulses and improves their shape in comparison with the pulse formation directly in the modulated active medium of an X-ray laser. The obtained analytical solution shows that the pulse formation in the modulated absorber is due to the existence of a multifrequency structure of the resonant radiation, which propagates in the medium without absorption. It is shown, both analytically and numerically, that the spectraltemporal characteristics of the pulses are insensitive to changes in the optical thickness of each medium (absorbing and amplifying) over a wide range. The possibility of forming X-ray pulses with a wavelength of the order of 3.4 nm, having a duration of less than 200 as and a peak intensity exceeding 10 13 W/cm 2 , in the plasma of hydrogen-like C 5+ ions is shown.

“…The high-power laser can produce ultra-short and ultrastrong pulses, and is widely used in many fields, for example, the fast ignition in inertial confinement fusion, [1] the study of laser-matter interactions, [2] and research into x-ray sources. [3] Due to laser-induced damage, the output capability of highpower laser facilities is mainly limited by the apertures of optics, including the non-linear crystal, compression grating and focusing terminal. So large-aperture optics is required to improve the output capability of high-power laser facilities.…”

Due to laser-induced damage, the aperture of optics is one of the main factors limiting the output capability of high-power laser facilities. Because of the general difficulty in achieving large-aperture optics, an alternative solution is to tile some small-aperture ones together. We propose an accurate, stable, and automatic method of array element tiling and verify it on a double-pass 1 × 2 tiled-grating compressor in the XG-III laser facility. The test results show the accuracy and stability of the method. This research provides an efficient way to obtain large-aperture optics for high-power laser facilities.
