Oxide-based nonlinear borate single crystals: a good challenge for the design of efficient UV solid state laser in the UV range

Gerard Aka

Chimie Paristech, France

Nowadays, only very few nonlinear (NLO) crystals can achieve Third harmonic or forth

harmonic generation phase matching process towards UV, especially when wavelengths below 270

nm are targeted. Therefore, the field of research for NLO materials in UV range is still widely open.

Reliable and long lifetime new NLO crystals would easily open industrial markets. More than

hundreds of non-centrosymmetric crystals have been investigated since 1962 regarding their

frequency conversion properties. However, the most materials that eventually came to the market

and found practical applications remain oxide-based borates single crystals

Nd doped LNOI has been fabricated from a diffusion doped LiNbO3 (LN) substrate. Diffusion doping allows to fabricate differently doped areas on a single LNOI substrate. The fluorescence spectra, the fluorescence lifetime and the small signal gain have been determined for the first time, to the best of our knowledge. The results obtained agree with data published for diffusion doped ridge or channel waveguides in LN substrates. We achieve a small signal gain of 16dB pumping with a DBR laser diode what is promising for future laser operation.

Domain walls (DWs) in ferroelectric materials are of highest interest as integrated functional elements, for instance in optoelectronic nanodevices. We investigate individual ferroelectric DWs in periodically-poled LiNbO3 single crystals by applying polarization-sensitive optical coherence tomography at 1300 nm. Using circular light polarization, we probe the relevant electro-optical properties close to and at the DWs. Comparing experimental results to simulations, we conclude that the three different DW signals are associated to the ordinary and extraordinary refractive index, and to a third contribution from the mean value of both.
