摘要
随着超连续谱激光技术水平的发展,超连续谱激光在大气传输中的应用越来越广泛。在实际应用中,大气与超连续谱光波相互作用,导致光强衰减、光传播方向偏折及光斑特征变化等,这些大气传输效应对超连续谱激光应用的影响是两方面的,一方面既影响了超连续谱激光的能量传输和成像效果,另一方面可以利用大气对超连续光谱的吸收特性进行大气多成分的同时测量。因此,只有在充分研究超连续谱激光的大气传输特性基础上才可能更好地开展超连续谱激光的应用研究。从目前超连续谱激光技术、超连续谱激光的空间相干特性、大气对超连续谱的吸收和湍流效应影响等方面介绍了超连续谱激光大气传输研究的现状,提出了应进一步深入研究的问题,并对未来的工作予以展望。
With the development of supercontinuum laser, more and more extensive applications of super-continuum laser received researchers＇ attention. Attenuation of light intensity, deflection of light propagationdirection, changes of spot characteristic and so on are cruised by the interaction of atmosphere and supercon-tinuum＇s light wave. The effect of supercontinuum propagation in atmosphere has two influences on super-continuum application. The advantage is that the absorption characteristics of supercontinuum can be usedto measure the concentration of various atmospheric constituents simultaneously. The disadvantage is thatit may effect the energy transmission and imaging of supercontinuum. So research of the characteristics ofsupercontinuum propagation in atmosphere is an urgent demand. According to the introduction of recentdevelopments in supercontinuum laser technology, spatial coherence properties, absorption characteristics andturbulence effects of supercontinuum laser, the prospect of future research work is put forward.
