Fluorescence of Ti(3+) ions thermally diffused into sapphire.
The thermal diffusion of Ti(3+) ions into sapphire is demonstrated, and the spectroscopic characteristics of the locally doped region are presented. The spectral line shape, polarization dependence, and excited-state lifetime of indiffused Ti:sapphire are in excellent agreement with previously published data for high-quality, bulk-doped Ti:sapphire laser crystals. The observed diffusion rate at...
متن کاملTItanium Sapphire Lasers
• In 1982 researchers at Lincoln Laboratory operated a tunable laser based on Ti:Al20 3 for the first time. A wide variety ofdevelopments in Ti:Alz0 3 1aser technology then followed the advances in crystal growth that occurred during the mid-1980s. Since that time researchers have demonstrated high efficiency, wide tunability, frequency-stable continuous-wave operation, and generation of very s...
متن کاملFemtosecond Laser Ablation of Sapphire
INSTRUCTION Sapphire is widely used in the field of optical components and micromechanical devices owing to its useful mechanical, optical, and electrical properties. However, sapphire is mechanically and chemically difficult to machine because of its high hardness and chemical stability. The difficulty of machining sapphire has restricted the development of advanced device structures. As sapph...
متن کاملRotational Reconstruction of Sapphire (0001)
The structure of the ( √ 31 × √ 31)R ± 9 reconstructed phase on sapphire (0001) surface is investigated by means of a simulation based on the energy minimization. The interaction between Al adatoms is described with the semi-empirical manybody Sutton-Chen potential, corrected for the charge transfer between the metallic overlayer and the substrate. The interactions between the Al adatoms and sa...
متن کاملDeep ultraviolet photodetectors grown by gas source molecular beam epitaxy on sapphire and AlGaN/sapphire substrates
Optically-based chemical and biological sensors require optoelectronic devices with specific emission and detection wavelength ranges. Semiconductor optoelectronic devices applicable to this sensing are of particular interest due to their low power consumption, compact size, long lifetime, and low cost. We report the electrical and optical properties of deep UV p-i-n photodiodes (PDs) based on ...
