Buried amorphous layers by electronic excitation in ion-beam irradiated lithium niobate: structure and kinetics

The formation of buried heavily damaged and amorphous layers by a variety of swift-ion irradiations (F at 22MeV, O at 20MeV, and Mg at 28MeV) on congruent LiNbO$_3$ has been investigated. These irradiations assure that the electronic stopping power …

Compositional Study of LiNbO$_3$ Thin Films Grown by Liquid Phase Epitaxy

Lithium niobate (LN) films have been obtained on pure congruent single-domain LN substrates by the liquid phase epitaxy technique. Li-rich flux of LiVO$_3$ has been used. The optimum temperature for the film preparation has been found to be 860°C. …

Electron-Phonon Coupling in Yb$^{3+}$:LiNbO$_3$ Laser Crystal

Electron-phonon coupling in Yb$^{3+}$:LiNbO$_3$ is studied by comparing the optical (absorption and emission) low-temperature spectra with the room temperature Raman spectrum of undoped LiNbO$_3$. As a result, the whole vibrational structure of the …

Multiple Stokes and Anti-Stokes Picosecond Generation, cw Laser Action at Wavelengths of Two Stimulated-Emission Channels $^4F_{3/2}$ $\rightarrow$ $^4I_{11/2}$ and $^4F_{3/2}$ $\rightarrow$ $^4I_{13/2}$, and Nanosecond Self-SRS Lasing in Undoped and Nd$^{3+}$-Doped Tetragonal PbMoO$_4$ Crystals

New Laser and $χ^{(3)}$-Nonlinear Properties of PbMoO$_4$:Nd$^{3+}$: CW Stimulated Emission at 1.0594 and 1.335 μm, High-Order Picosecond Raman Generation, and Nanosecond Self-SRS Lasing

Structure of High Index Proton Exchange LiNbO$_3$ Waveguides with Undegraded Nonlinear Optical Coefficients

A structural study is presented on proton exchanged LiNbO$_3$ waveguides prepared in benzoic acid vapor which, for $z$-cut substrates, were previously reported to simultaneously exhibit high index jump, very low losses, and undegraded nonlinear …
