INVESTIGATION OF NONLINEAR OPTICAL RESPONSES OF BOVINE SERUM ALBUMIN AND SOME AMINO ACIDS USING Z-SCAN TECHNIQUE
(Shahjalal University of Science and Technology(SUST), 2023-07)The Z-scan technique is a relatively simple but sensitive technique for studying third-order Nonlinear optical effects in materials. In this research work, we have implemented the continuous wave (CW) ... -
Multiple Beam Interferometry for Third Order Optical Nonlinearity
(2017-08)An experimental research work has been done to estimate the nonlinear refractive index of 2, 5 - dimethylaniline (DMA) by multiple (three) beam interferometry using a Mach-Zehnder interferometer. 2, 5 - dimethylaniline was ... -
Spin Lattice order in frustrated Nickel- Zinc-Chromite (Ni x Zn 1-x Cr 2 O 4 ) System
(Shahjalal University of Science and Technology(SUST), 2016-04)ZnCr 2 O 4 compound is well known to show the frustration of the spin structure. At 12 K, ZnCr 2 O 4 distorts to break symmetry of the degenerated frustrated spin states by the spin- Peierls-like phase transition, ... -
A study of quality of different kinds of bricks and other building materials available in Bangladesh using neutron radiography technique and design of a small scale neutron radiography facility
(Shahjalal University of Science and Technology(SUST), 2015-10)Manufacturing building materials has become very good option of business in the developing countries like Bangladesh. Quality control of these materials and environmental friendly structure assurance ... -
Third Order Optical Nonlinearity with Far Field Diffraction Rings
(SUST, 2017-08)An experimental work has been done to study the third order optical nonlinearity of 2,5- dimethylaniline (DMA). The nonlinear phase shift and the nonlinear refractive index of DMA were estimated using the Far Field ... -
Wigner Rotation in Flat Space, Hyperbolic Space and the Outer Space of a Schwarzschild Black Hole
(Shahjalal University of Science and Technology(SUST), 2020-02)We have represented Lorentz transformation and its consequences, i.e. time dilation and length contraction. The velocity addition formula has also explained. The formula of the transformation of orbital angular ...
