Many applications of THz radiation require high fields and high repetition rates at the same
time, implying substantial average power levels. Here, we report high-power Cherenkov …

Various manifestations of small polarons strongly affect the linear and nonlinear optical
properties of the oxide crystal lithium niobate (LiNbO 3, LN). While related transient …

The formation and relaxation dynamics of electron polarons in lithium niobate crystals were
investigated by measuring transient absorption induced by blue femtosecond pulses …

A comparative study on the light-induced absorption was performed for lithium niobate and
lithium tantalate crystals in which the antisite defects were eliminated by MgO doping. The …

Femtosecond-pulse-induced (E_pump= 2.5 eV) picosecond infrared absorption is studied in
the spectral region between 0.30 eV and 1.05 eV in LiNbO_3: Mg. We find a non …

We study the statistical distributions of the output signals of a superconducting hot-electron
bolometer (HEB) detector exposed to weak photon pulses of 1 THz (terahertz) frequency …

We probe here the optical relaxation properties of Mg-doped wide-band-gap LiNbO 3 single
crystals with both a high spectral and temporal resolution at cryogenic temperatures …

We investigate light-induced heating by nonlinear absorption in LiNbO 3-type crystals under
continuous-wave (CW) laser irradiation. The heat source is one-photon absorption by long …

Dielectric constant, thermally stimulated depolarization currents (TSDC), and conductivity of
undoped and 5% Mg-doped LiNbO 3 single crystals between− 100 C and 200 C have been …

Transient characteristics of upconverted emission (560 nm) of Er 3+ in LiNbO 3 crystals
codoped with 0–7.4 mol% MgO were studied under pulse excitation at 800-nm wavelength …
