Special Issue Information

Dear Colleagues,

Laser devices have become essential for a wide range of modern machines, which can be used in a wide range of fields, such as medicine, biology, micromachining processes, industrial manufacturing and high-precision sensing equipment. Due to the intensive applications of laser devices, it can be expected that the demand for new devices, performance enhancement, size reduction, control and stability will be permanently required. This implies that research in the physics and technology behind laser device fabrication and implementation will be quite intensive and valuable. Moreover, edge technology in electronics, control and mechatronics is required to implement practical and functional machines that use laser devices. Furthermore, laser devices can be used in combination with optical components to implement high-performance sensing equipment.

This Special Issue is intended to provide a multidisciplinary forum where researchers and engineers can present their recent advances in the modelling, design and fabrication of laser devices. Additionally, this forum is open to presenting theoretical designs and experimental results of laser sensors. Additionally, in this Special Issue, we welcome works in the field of laser devices stabilization (e.g., intelligent current and temperature drivers, mechatronics actuators).

Topics include, but are not limited to, the following domains:

  • Laser physics;
  • Microfabrication of laser devices;
  • Power lasers;
  • Fiber optic lasers;
  • Solid-state lasers;
  • Pulsed and continuous-wave lasers;
  • Unconventional cavity lasers;
  • Quantum properties of laser light;
  • Design and implementation of laser sensors;
  • Current drivers for solid-state lasers;
  • Temperature drivers for laser applications.

Abstract
A stable, single, and dual-wavelength erbium-doped fiber laser (EDFL), based on two Mach–Zehnder interferometers (MZIs), arranged in a cascade configuration, was proposed for experimental purposes. Both MZIs were assembled by splicing a capillary hollow-core fiber (CHCF) section between two multimode fibers (MMFs) segments. [...] Read more.
A stable, single, and dual-wavelength erbium-doped fiber laser (EDFL), based on two Mach–Zehnder interferometers (MZIs), arranged in a cascade configuration, was proposed for experimental purposes. Both MZIs were assembled by splicing a capillary hollow-core fiber (CHCF) section between two multimode fibers (MMFs) segments. The novelty of this single and dual-wavelength EDFL is that the switchable operation of the laser is achieved by thermally tuning the interference pattern of one MZI and not by adjusting the polarization state inside the fiber ring cavity. The maximum measured value of SNR was 58.9 dB for the single and dual-wavelength laser emissions. Moreover, the stable output power exhibited by this EDFL, in terms of minimal power and wavelength fluctuations, at 0.05 dB and 10 pm, was detected during the single and dual-wavelength operation. It is worth noticing that switching is achieved at exact wavelength locations with a separation of 1.8 nm and not randomly, as reported by other works. These features make this switchable EDFL an appealing candidate for application in optical fiber communication systems and fiber sensing. Full article
