The use of microstructured crystals in quasi-phasematched (QPM) nonlinear interactions
has enabled operation of nonlinear devices in regimes inaccessible to conventional …

The development of nonlinear optical (NLO) borate crystals for generation of visible and UV
light is reviewed. We first discussed on the basic principles of laser frequency conversion …

Nonlinear optical techniques are now recognized as the most efficient means available to
generate laser radiation at wavelengths that are presently inaccessible via conventional …

Fourier-transform infrared spectroscopy (FTIR) is an indispensable analytical method that
allows label-free identification of substances via fundamental molecular vibrations …

Highly correlated photons or, accordingly, high-fidelity single-photon states are a
prerequisite for closing detection loopholes in experimental tests of local realism and …

An overview of optical nonlinearities of small bound polarons is given, which can occur in
the congruently melting composition of LiNbO 3. Such polarons decisively influence the …

The frequency doubling of a 110-W linearly polarized diffraction-limited Yb-doped fiber
oscillator power amplifier (FOPA) has generated 60-W near-diffraction-limited M 2≤ 1.33 …

We present a study of orbital angular momentum transfer from pump to down-converted
beams in a type-II optical parametric oscillator. Cavity and anisotropy effects are investigated …

We demonstrate a bright, bandwidth-tunable, quasi-phase-matched single-waveguide
source generating photon pairs near 900 nm and 1300 nm. Two-photon coincidence spectra …

Temperature calibrated piezoelectric resonances of internal acoustic vibration modes of a
nonlinear-optical crystal during its heating by high-power laser radiation are used for …
