Nanosecond time - resolved spectroscopy 毫微秒時間皆辨率光學
Generation of multi - wavelength signals and ultra - short pulses are of great importance for a wide range of applications such as in wavelength - division - multiplexed ( wdm ) and optical time - division - multiplexed ( otdm ) fiber communication systems , fiber sensing , nonlinear optics , optical instrument testing , and time - resolved spectroscopy 密集波分復用( dwdm )和光時分復用( otdm )是實現光纖通信系統升級擴容的有效途徑,而多波長信號及高重復頻率的超短光脈沖的產生則是與其相對應的兩種關鍵技術。
百科解釋
In physics and physical chemistry, time-resolved spectroscopy is the study of dynamic processes in materials or chemical compounds by means of spectroscopic techniques. Most often, processes are studied after the illumination of a material occurs, but in principle, the technique can be applied to any process that leads to a change in properties of a material.
