Quasi-phase matching optical parametric oscillators (OPOs) are widely used for mid-infrared laser generation. However, the traditional OPO bulk material using high voltage electric field poling limits the flexibility of the poling period. In this pap

Thermal effects strongly influence the process of second harmonic generation, especially at high fundamental powers. The generation of non-uniform temperature distribution in the crystal due to the absorption of fundamental and second harmonic waves

We have derived a novel equation to accurately predict the third harmonic generation (THG) conversion efficiency in hybrid periodically poled nonlinear medium. Our equation considers the general case that takes both depleted pump regime and phase mis

Azo compounds, which are highly versatile molecules, have attracted a considerable attention both for their fundamental properties and for practical applications, especially in photonics. The conjugated azo-aromatic systems containing 4-(R-azulen-1-y

A multi-wavelength bandstop filter is proposed and numerically demonstrated using the sum-frequency generation (SFG) process in a waveguide of periodically poled lithium niobate (PPLN). This proposed device achieves channels number reconfigurable, ce

In this work we provide for the first time a novel and more accurate second harmonic generation (SHG) conversion efficiency equation for periodically poled nonlinear medium. We believe the equation derived in this work is more useful than equations r
