The lithium-niobate-based waveguides have emerged as one of the key platforms for
enabling integrated optical technologies. The most common method for creating …

We carry out a theoretical investigation of the backward interaction optical parametric
oscillator (OPO), in which one of the generated waves is counterpropagating with respect to …

Lithium niobate LiNbO 3 (LN) on insulator wafers (LNOI) representing a submicron-thick LN
film bonded to a SiO 2 layer deposited on a thick LN substrate have been manufactured …

The analysis of the shapes of Barkhausen pulses (BPs) was used for the detailed
characterization of the domain merging process in congruent lithium niobate LiNbO 3 (CLN) …

Backward electromagnetic waves are extraordinary waves with contra-directed phase
velocity and energy flux. Unusual properties of the coherent nonlinear optical coupling of the …

In this paper, we report a theoretical systematic study of continuous wave intracavity
backwards optical parametric oscillators based on periodically poled lithium niobate (PPLN) …

Nonlinear generation and manipulation of vortex beams have been emerged as a research
hot topic in recent years. During the nonlinear frequency conversions, the orbital angular …

In this paper, a diode pumped mid-IR laser based on a singly resonant intracavity
backwards optical parametric oscillator (SR IC-BOPO) is proposed and a simulation model …

The periodical domain structure with period 2 μm was created in 1-mm-thick MgO doped
lithium niobate single crystals by electron-beam irradiation. The second harmonic …

We present a simple, compact source of sub-nanosecond pulsed red radiation, based on
cascaded nonlinear optical processes—degenerate optical parametric generation and sum …
