Study of Refractive index on non linear optical material of Potasium dihydrogen phosphate, Potasium titanyl phosphate, Potassium niobate
نویسندگان
چکیده
Refractive indices for the crystals potassium dihydgrogen phosphate, potassium titanyl phosphate and potassium niobate are measured. Samples of KDP from different crystal growers had slightly different refractive indices. The refractive indices of KDP for ordinary rays are studied as a function of temperature. The temperature coefficient of the refractive indices has little dependence on the wavelength. From the data obtained the refractive indices and their dependence temperature, wavelength and pressure are discussed.

Glassy samples with a composition of 40P2O5–30V2O5–(30-x)Li2O– xK2O, 0<x<30 (mol %) were prepared by the conventional melt quenching technique in two forms of bulk and blown film. X-ray diffraction patterns corroborated the amorphous feature of the samples. Density of samples was investigated by using Archimedes principle. Based on absorption and reflection spectra, indirect a...

In this paper, an optical angle sensor with a birefringent transducer for measuring angular displacement based on a heterodyne interferometry is proposed. The achievable repeatability and linearity provide sufficient evidence for the practical use. As a result, a resolution of 5.8 ˆ 10 ́6 with a dynamic range of 5 ̋ has been achieved by utilizing a KTP (potassium titanyl phosphate) plate immersed...

متن کاملGeneration of ultra-broadband pulses in the near-IR by non-collinear optical parametric amplification in potassium titanyl phosphate.
Non-collinear optical parametric amplification in potassium-titanyl phosphate (KTP) pumped with 800 nm pulses is reported. Broadband phase matching is achieved with non-collinear geometry and a slightly divergent signal seed. This enables a gain bandwidth up to approximately 2500 cm(-1) in near-IR region. Introducing a chirp into the pump pulse makes it possible to amplify the white light seed ...
