The results indicate that gallium nitride materials exhibit saturable absorption properties in a wide spectral range especially in the ultraviolet and visible light bands making them suitable for desi

The findings suggest that gallium nitride materials possess saturable absorption characteristics across a broad range of wavelengths, particularly in the ultraviolet and visible light regions. This makes them ideal for developing Q-switching devices for frequency-doubled lasers and ultraviolet lasers. These materials show significant potential for application in laser modulation of crystals like Ce:BaY2F8, Ce:KY3F10, and Ce:LiYLuF4, which addresses the shortage of Q-switching materials for ultraviolet lasers.
