A new theoretical approach towards the tuning of Goos–Hänchen shift and Imbert–Fedorov shift for the reflected light beam is observed, designed and simulated in this paper through electro-optically tunable liquid crystal at an incident wavelength of 1550nm within the communication window. Here the considered Kretschmann–Raether geometry comprises a ZnSe prism and a liquid crystal layer of E44 between...
We report the first, according to our knowledge, experiment for direct third harmonic (TH) generation in periodically poled quadratic crystals. TH radiation of a diode array pumped and acousto-optically Q-switched Nd:YVO 4 laser is generated in a 25mm long periodically poled lithium niobate (PPLN) crystal of period 7.0μm. A theoretical model is developed that explains the experimental results...
