Special Issue Information

Dear Colleagues,

Laser technology is one of the great achievements of the 20th century. Over the past 50 years, due to the rapid development of laser technology and applications, significant breakthroughs have been made in basic scientific research such as laser cooling, semiconductor lasers, optical frequency combs, laser interference gravitational wave detection, chirped pulse amplification, and optical tweezers. At the same time, a series of new interdisciplinary and technological applications have been raised by laser technology, including laser spectroscopy, laser chemistry, quantum optics, ultrafast photonics, nonlinear optics, laser medicine and biophotonics, information optoelectronics, laser advanced manufacturing technology, laser controlled nuclear fusion technology and so on.

At present, laser technology is still one of the most promising frontier technologies and has a wide range of applications in industrial manufacturing, scientific research, precision measurement and military defense, etc. New laser light sources are generally developing towards higher power, higher brightness, higher speed, higher pulse energy, shorter pulse width, narrower line width, and wider wavelength range (extreme ultraviolet and mid-infrared wavelengths). The rapid development and wide application of next-generation laser technology will be based on cutting-edge breakthroughs in new laser materials and devices. Researchers are invited to submit their contributions to this Special Issue. Topics include, but are not limited to:

  • High-power laser
  • High-brightness laser
  • Ultrashort pulse laser
  • Attosecond laser technology
  • Narrow linewidth
  • Single-frequency laser
  • Frequency combs
  • Ultraviolet laser
  • Mid-infrared laser
  • Semiconductor lasers

He-Ne lasers play a crucial role in ultra-precision measurement and optical sensing across various fields. For many applications based on He-Ne lasers, a higher output power is required to enhance the accuracy and signal-to-noise ratios of the associated optical measurements. However, conventional methods to increase the output power by reducing the diameter of the He-Ne laser discharge capillary inevitably result in higher diffraction losses and constrain the lasing performance. Here, we propose an approach to enhance laser pumping efficiency and output power through optimizing the ratios of He and Ne gasses. The validity of our proposal has been confirmed by both numerical simulations of He-Ne laser plasma discharge processes and experimental demonstrations, showing that the optimal gas ratio increases with the capillary diameter and total gas pressure.
