Special Issue Information

Dear Colleagues,

The generation of ultraviolet lasers, or laser-like coherent light sources in the ultraviolet range, often has a strong impact on both fundamental research and applied industrial applications. Ultraviolet optical sources are the only means of providing some unique optical properties, including an extremely short wavelength, a broad frequency bandwidth, high photon energy, and high levels of interaction with almost all materials. These optical properties are critical for the development of many emerging techniques, including super-resolution imaging and lithography, multi-octave and few-cycle laser pulse generation, cold ablation and heat-affected zone free machining, highly sensitive atomic emission spectroscopy and selective sterilization.

These novel techniques further promote the development of a wide range of applications in multiple disciplines, including advanced semiconductor manufacturing, femto/atto-physics and chemistry, precision biology and medicine.

The aim of this Special Issue is to encourage researchers to report their latest achievements in the generation of novel ultraviolet laser sources or the exploration of new properties and the potential applications of these novel ultraviolet lasers. The scope of this Special Issue includes, but is not limited to, the following topics:

  • Fourth to sixth harmonic generation for UV laser generation;
  • UV laser-based micro and nanofabrication;
  • Super resolution imaging and tomography using UV laser;
  • Application of Ultraviolet Laser Working in Cold Ablation;
  • Heat-affected zone minimization; 
  • Nano particle and graphene synthesis using UV laser;
  • Nano-resolution additive manufacturing using UV polymerization;
  • DUV disinfection and sterilization;
  • UV spectroscopies for material characterization;
  • UV breakdown spectroscopy for environmental monitoring;

In this paper, a high-repetition-rate, high-peak-power burst-mode nanosecond 355 nm UV laser was demonstrated. A quasi-continuous wave (QCW) laser diode (LD) side-pumped electro-optical (EO) Q-switched burst-mode Nd: YAG laser was performed as the fundamental laser source. Under the pumping duration of 250 μs and a burst repetition rate of 100 Hz, the pulse energy of 20 kHz burst-mode UV laser reached 5.3 mJ with a single pulse energy of 1.325 mJ, pulse width of 68 ns, resulting in a peak power of 19.49 kW. The as-generated millijoule burst-mode UV laser has great potential for high-end processing of laser lift-off, annealing and slicing in display semiconductor fields. Full article

Photocathode laser pulse shaping is a crucial technology for enhancing the performance of X-ray free-electron lasers by optimizing the quality of electron beams generated from photocathodes within high-gradient radio frequency guns. By precisely shaping these laser pulses, it is possible to significantly reduce the transverse emittance of produced electron bunches. The optimal pulse shape is an ellipsoidal distribution, commonly referred to as the Kapchinskij–Vladimirskij profile. A pulse-shaping scheme utilizing a commercial Yb:KGW laser operating at 514 nm with a repetition rate of 1 MHz and duration of 260 fs has been developed for generating electron bunches with high peak and average power. This study presents the experimental realization of ellipsoidal pulses via three-dimensional amplitude shaping using spatial light modulators at 514 nm, followed by conversion to UV (257 nm) suitable for Cs 2Te photocathodes. The preservation of pulse shape and a high conversion efficiency during this process are investigated and our experiments pave the way for future emittance minimization for X-ray free-electron lasers.

The paper proposes a method for the calibration of spacing in dual-grating based on Multiple Improved Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (ICEEMDAN) combined with Hilbert Transform (HT), referred to as Multiple ICEEMDAN-HT. This method addresses the potential impact of nonlinear factors on phase extraction accuracy, consequently on ranging precision in the homodyne interference of the dual-grating. Building upon the ICEEMDAN algorithm, the signal undergoes iterative decomposition and reconstruction using the sample entropy criterion. The intrinsic mode functions (IMFs) obtained from multiple iterations are then reconstructed to obtain the complete signal. Through a simulation and comparison with other signal decomposition methods, the repeatability and completeness of signal reconstruction by Multiple ICEEMDAN are verified. Finally, an actual dual-grating ranging system is utilized to calibrate the spacing of the planar grating. Experimental results demonstrate that the calibration relative error of the Multiple ICEEMDAN-HT phase unwrapping method can be reduced to as low as 0.07%, effectively enhancing the signal robustness and spacing calibration precision.
