Abstract The paper reports the efficient terahertz generation using nonlinear optical rectification process and comparative studies of optical, dielectric, surface scattering properties 1.0 mm thin GaSe: S crystal in transmission/reflection modes. We employed 800 nm wavelength 140 fs 50 pulse durations obtained from Ti: Sapphire oscillator amplifier systems at 80 MHz 1 kHz repetition rates, respectively, evaluated THz potential such as refractive index, absorption coefficients, relative...
This paper reports the linear and nonlinear optical characterization of α-TeO2 crystal in terahertz domains for efficient (THz) generation using a difference frequency mixing technique. We have ascertained properties such as refractive index, absorption coefficients, real imaginary dielectric constants, coherence length lc=280mm at 1.77 THz range an indigenously developed spectrometer. The value index was from temporal spectral profiles employed calculating Type I phase-matching angle, i.e.,...

We report the time domain THz-based optical evaluation of different sized soil samples obtained from jungle and defense test range country. The testing exercise using reflection mode time-domain terahertz (THz) spectroscopy technique is related to development a small THz radar system. study helps us understand role particles in terms identifying presence minerals /ores including organic explosives contaminants. E-M waves between 0.1- 4.0 provide significant information origins refractive...
Terahertz (THz) technology integration with nanomaterials is receiving excellent attention for next-generation applications, including enhanced imaging and communication. The optical properties in THz domain can lead to make low-cost CMOS camera which convert radiation into signal very efficient manner. In present study, we demonstrate the conversion of terahertz signals from at room temperature using Zinc Sulfide quantum dots (ZnS QDs) embedded Polyvinyl Alcohol (PVA) composites, as a model...
The paper reports the terahertz time-domain spectroscopy of 3, 4, 5 -Trinitro 1-H Pyrazole (explosive) between 0.1-1.5 THz range. We ascertained values refractive index and absorption coefficients in solid powder form.
