Nanosecond time - resolved spectroscopy 毫微秒時(shí)間皆辨率光學(xué)
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(fù)用( dwdm )和光時(shí)分復(fù)用( otdm )是實(shí)現(xiàn)光纖通信系統(tǒng)升級(jí)擴(kuò)容的有效途徑,而多波長(zhǎng)信號(hào)及高重復(fù)頻率的超短光脈沖的產(chǎn)生則是與其相對(duì)應(yīng)的兩種關(guān)鍵技術(shù)。
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.
