Abstract

The invention of the laser in 1960 created the possibility of using a source of coherent light as a transmitter for a laser radar (ladar). Coherent ladar shares many of the basic features of more common microwave radars. However, it is the extremely short operating wavelength of lasers that introduces new military applications, especially in the area of missile identification, space target tracking, remote rang finding, camouflage discrimination and toxic agent detection. Therefore, the most popular application field such as laser imaging and ranging were focused on CO₂ laser in the last few decades. But during the development of solid state and fiber laser, some people said that the CO₂ laser will be disappeared and will be replaced by the solid and fiber laser in the field of military and industry. The coherent CO₂ laser radar will have the same destiny in the field of military affairs. However, to my opinion, the high power CO₂ laser will be the most important laser source for laser radar and countermeasure in the future.
