Therefore, the need to develop a new multi-mode fiber, an 850nm laser-optimized fiber. Even with this new fiber, another RML bandwidth test methods can not completely guarantee the 10Gbit / s, 300 m of transmission. To meet the requirements on the transmission speed and transmission distance, it is only the mode of the fiber dispersion to reduce to an unprecedented level, which requires more fundamental measurement mode dispersion. TIA and IEC[......]

This cooling is known as the Doppler cooling, the cooling force is called the dissipative force or spontaneous radiation. Absorption and emission times per second, this retarding force is great, For 589nm the resonance light in sodium atoms, the slowing effect is equivalent to 100,000 times the acceleration due to gravity [2] atoms along the x-axis for a dimensional random movement, speed, big and small, both positive and negative direction of[......]

Of course, this is under the assumption that isotope pumped level to upper level relaxation rate similar conclusions. In general, the isotopes in the transition rates are similar. If corresponding by stimulated transition, in general, the broadening of spectral lines is not conducive to gain the improvement of the laser oscillation; for some urgent need to expand the laser light with the situation, the lines widen or be of value. Isotopic line[......]
