Continuous‐wave and cavity‐dumped 1064 nm Nd:YVO4 laser based on the magneto‐optical effect

IET Optoelectronics, Volume 19, Issue 1, January/December 2025.
In this paper, the authors investigate the use of the magneto‐optical effect to control and optimise the output characteristics of continuous‐wave and cavity‐dumped Nd:YVO4 lasers. The study shows that by adjusting the magnetic field intensity, the authors can effectively regulate the laser's output power, pulse width, and waveform providing a ...

Study of the Verdet constant of the holmium-doped silica fiber

OSA Continuum, 2020
A Ho-doped silica fiber with a high verdet constant is prepared by a modified chemical vapor deposition (MCVD) method. The phenomenon of the Faraday effect enhancement of a Ho-doped silica fiber is theoretically analyzed by the wave transition contribution analysis method based on the wave-particle duality of light.

Magneto‐optical effect of rare‐earth‐rich borate glasses prepared using a levitation technique

Journal of the American Ceramic Society, Volume 107, Issue 12, Page 8126-8131, December 2024.
Abstract The magneto‐optical properties of rare‐earth‐rich borate glasses prepared using a levitation technique were thoroughly investigated. Among the series of rare‐earth borate glasses, Tb2O3–B2O3 and Dy2O3–B2O3 glasses displayed remarkably large Faraday effects in the visible region. The Verdet constant of 58Tb2O3–42B2O3 reached −229 rad/T·m at 633

Large Mid‐Infrared Magneto‐Optic Response from Doped Cadmium Oxide at Its Epsilon‐Near‐Zero Frequency

Advanced Optical Materials, Volume 12, Issue 25, September 3, 2024.
The high plasmonic quality of doped CdO is shown to enhance its magneto‐optic response near the epsilon‐near‐zero frequency, leading to a large peak in the Verdet constant that can be tuned throughout the mid‐infrared. The ability to deposit CdO on Si with no loss in performance makes this material a promising platform for integrated mid‐infrared ...

A Review: Active Tunable Terahertz Metamaterials

Advanced Photonics Research, Volume 5, Issue 7, July 2024.
GA: The diversity and practical significance of terahertz metamaterials have been rapidly developed in recent years, and the controllable properties are of great value. This review classifies the actively regulated terahertz metamaterials, divides them into four categories with external excitation as the classification standard, and presents some ...

Extreme Nonreciprocity in Metasurfaces Based on Bound States in the Continuum

Advanced Optical Materials, Volume 12, Issue 1, January 4, 2024.
Nonreciprocity is a crucial property of many optical systems. Magneto‐optical materials are usually used to implement these devices. However, this class of materials presents weak effects at optical frequencies. In this work, a metasurface supporting bound states in the continuum enhances magneto‐optical effects and its nonreciprocal response.
