Special Issue Information

Dear Colleagues,

Laser technology is widely used and has enabled significant progress in both laser technology itself and various laser application fields, such as industrial, medical, commercial, scientific research, and information. Lasers have continuously made breakthroughs in areas such as high power, narrow pulse width, wavelength tuning, and high beam quality, which also promoted technological progress in fields such as laser detection and processing. In short, there are many noteworthy advancements and breakthroughs in laser technology and applications.

This Special Issue on “Advances of Laser Technologies and Their Applications” discusses the recent efforts and advances made for laser technology and its various applications. We welcome scientific contributions in this domain, including (but not restricted to) the following:

  • Advanced laser technology;
  • LiDAR, advanced technologies, and methods in the field of laser ranging and imaging;
  • High-precision and high-sensitivity spectral detection technology;
  • The advanced laser processing technologies, such as laser welding, laser machining interior contour, laser cutting, and laser carving;
  • Advanced photodetectors;
  • Advanced beam shaping technology;
  • Data processing methods and technologies in the field of laser applications.

Abstract
In this paper, the results of a Particle-in-Cell (PIC) simulation of electrons accelerated using a 10 fs Top-hat (TH) beam with a limited pulse energy of 85 mJ, focused on a double nozzle gas target using an off-axis parabola (OAP), an axiparabola (AXP), [...] Read more.
In this paper, the results of a Particle-in-Cell (PIC) simulation of electrons accelerated using a 10 fs Top-hat (TH) beam with a limited pulse energy of 85 mJ, focused on a double nozzle gas target using an off-axis parabola (OAP), an axiparabola (AXP), and an axiparabola with additional spatial–temporal coupling (AXP+STC), are discussed. The energy of accelerated electrons was predominantly determined through self-focusing and the ionisation injection effects of the laser beam propagating in plasma. The maximal energy of electrons accelerated using an AXP+STC could be higher by 12% compared to the energy of electrons accelerated by the regular OAP. Full article

The Streak-Tube Imaging Lidar (STIL) has been widely used in high-precision measurement systems due to its ability to capture detailed spatial and temporal information. In this paper, we proposed a ranging measurement method that integrates a Time-to-Digital Converter (TDC) with a streak camera in a remote STIL system. In this method, the TDC accurately measures the trigger pulse time, while the streak camera captures high time-resolution images of the laser echo, thereby enhancing both measurement accuracy and range. A corresponding ranging model is developed for this method. To validate the system’s performance, an outdoor experiment covering a distance of up to 6 km was conducted. The results demonstrate that the system achieved a distance measurement accuracy of 0.1 m, highlighting its effectiveness in long-range applications. The experiment further confirms that the combination of STIL and TDC significantly enhances accuracy and range, making it suitable for various long-range, high-precision measurement tasks.
