A review of lithium niobate single crystals and polycrystals in the form of powders has been
prepared. Both the classical and recent literature on this topic are revisited. It is composed of …

Lithium niobate-silica fibers were produced by the combination of the sol-gel method and
the electrospinning technique. Two sol-gel solutions starting from niobium-lithium ethoxide …

We report a compact, simple source of terahertz radiation that can be tuned to well-defined
frequencies spanning∼ 1.4 to 10 THz, based on difference-frequency generation in an HMQ …

We present a simple method to design aperiodically poled crystals to obtain multiple
nonlinear optical processes simultaneously. We use this technique to design and make an …

We present a compact source of sub-nanosecond infrared laser pulses. The system is a
diode-pumped, passively Q-switched Nd: YLF laser that emits 1.047 µm pulses with a …

We present a pulsed RGB source based on cascaded nonlinear processes that occur inside
a single crystal of PPLN with two poling periodicities placed in tandem. The first periodicity …

We present a Sellmeier equation that describes the refractive index dispersion of
congruently grown LiTaO 3, accurate from 0.3 to 5 μm and from 23 to above 200° C. Data …

We present a device, similar to a Shack–Hartmann sensor, that can detect both the intensity
distribution and wavefront of an incident wave. Its operation is based on the use of an array …

We report a device that acts as an active Q-switch and a quasi-phase-matching structure. It
is a domain-structured LiNbO_3 crystal, where the Q-switching is performed by electro-optic …

We present a scheme for conversion of pulsed light from the infrared to the red spectral
region, using an aperiodically poled ferroelectric crystal within a resonant cavity in which two …
