Rate adaptive multilevel coded modulation with high coding gain ... Rate adaptive multilevel coded modulation with high coding gain in intensity modulation direct detection optical communication
Generation of concentric multi-ring laser beam pattern with dif ... A method to shape the incident laser beam into a concentric multi-ring pattern with different intensity distribution is presented based on geometrical transform method and energy conservation. The output two and three rings are designed as examples to ...
The Relationship between Amplitude of Motor Evoked Potentials an... The Relationship between Amplitude of Motor Evoked Potentials and the Stimulation Intensity of Transcranial Magnetic Stimulation
Flat-top optical frequency comb generation based on optical fibe... ... frequency conversion and optical fiber-loop modulation is proposed and demonstrated experimentally. Flat-top optical pulse train from an intensity modulator is injected into a fiber loop, which includes a phase modulator and an amplifier and is cyclically ...
Spectral evolution of NIR luminescence in a Yb3+-doped photonic ... ... drawn photonic crystal fiber (PCF) has a strong absorption at 976 nm and emission wavelength of approximately 1 037 nm. The intensity and spectral lineshape of the near infrared (NIR) luminescence of the Yb3+-doped PCF are recorded and discussed in terms ...
Intense Femtosecond Laser Interaction with Large Size Argon and ... ... scattering measurements and found to follow roughly a P^{2.0}_0 scaling with the gas backing pressure P0. At P0=20 atm, the average size of the argon clusters was estimated to be about 3000 atoms per cluster. The laser intensity was variable, with 7
Spectroscopic Study of Ne Clusters Irradiated by an Intense, Fem... X-ray emission (4~18 nm) from small-sized Ne clusters heated by high-intensity, 25~100 fs laser pulses is spectroscopically inverstigated. The Ne spectrum started to drastically change in emitting ions from Ne5+ to Ne7+ below the pre-expansion temperature ...
Nonlinear Optical Response from Co magnetic thin films ... the magnetic Co thin films was studied by magnetization-induced second harmonic generation (MSHG). The magnetic contrast in MSHG intensity could be clearly distinguished for the cobalt films prepared by both sputtering and molecular beam epitaxy, but the ...
Absorption and Emission Characteristics of Highly Er3+ Doped Gla... ... at 0. 80 μm and 0. 98 μm were investigated and compared. Experimental results show that the Er3+: AYF glass has a smaller concentration quenching and much stronger intensity of the 1. 54 μm emission. In high dopant, the 1. 54 μm emission in Er3+: AYF glas
Influence of Turbid Medium Parameters on Back Scattered Intensit... In this paper, we simulate a practical in vivo technique in which is produced influence of turbid medium parameters on backscattered intensity and pulsewidth of picosecond for turbid tissue surface of a semi in fin ite medium by a small narrow linewidth ...
