We report the successful development of an all-solid state laser based on a Czochralski method-grown cerium-doped lithium calcium aluminum fluoride (Ce3+:LiCaAlF6 or Ce:LiCAF) crystal as the gain medium. Results for the broadband, narrow linewidth and sho... see more

We report on a Chirped Pulse Amplification (CPA)-based Titanium:Sapphire (Ti:Al2O3 or Ti:Sapphire) amplifier that uses a single grating stretcher and compressor configuration. The 8-pass amplifier configuration is able to yield 70 µJ pulse energy at 10 Hz... see more

We report a design of a cerium-doped lithium calcium hexafluoro aluminumate (Ce:LiCaAlF6_{6}, Ce:LiCAF) laser resonator based on total internal reflection (TIR). This TIR configuration is established by placing the Ce:LiCAF crystal between two calcium flu... see more

In the framework of the semiclassical theory, we develop an analytical approach on electromagnetically induced transparency (EIT) in the medium consists of five-level cascade scheme of cold 85Rb atoms. In the weak field limit of the probe light, an analyt... see more

In this paper, we report results on the fabrication and magnetic properties of spinel ferrite Mn1-xZnxFe2O4 (0 = x = 0.8) nanoparticles. The nanoparticles were synthesized by a co-precipitation method. The effects of substituting Zn for Mn on the magnetic... see more

In this study we report the effect of sintering temperature on the low field magnetoresistance(LFMR) of La0.7Ca0.3MnO3 manganite synthesized through sol-gel technique. TheLa0.7Ca0.3MnO3 has been sintered at 600°C, 700°C, 800°C, 900°C and 1200°C. The cryst... see more

The national policy of agricultural restructuring plays a vital role in adapting to climate change's effects and economic development in the Mekong Delta of Vietnam. Unproductive areas have been converted into other crops with higher efficiency. Drawn by ... see more
