Widely unable dual-wavelength operation of Tm:YLF, Tm:LuAG, and Tm:YAG lasers using off-surface optic axis birefringent filters
(Optical Soc Amer, 2018)
In this work, we have demonstrated dual-wavelength continuous-wave laser operation in diode-end-pumped Tm:YLF, Tm:LuAG, and Tm:YAG lasers. A 3-mm-thick quartz birefringent filter with an optical axis 45 degrees to the ...
Experimental investigation of coaxial impinging air jets
(Pergamon-Elsevier Science Ltd, 2018)
This study experimentally investigates hydrodynamical and thermal characteristics of coaxial confined impinging turbulent air jets. Various values of the dimensionless nozzle-to-plate distances and dimensionless flowrate ...
Peak-to-average-power-ratio (PAPR) reduction methods with wavelet transform in MIMO-OFDM
(Taylor & Francis Ltd, 2018)
This study is based on the comparison of the results with an analysis method recommended for the Peak-to-Average-Power-Ratio (PAPR) reduction methods. This is one of the most significant problems in the Multiple Input-Multiple ...
