Atmospheric monitoring is traditionally carried
out by contact and remote methods [1, 2]. Despite the
wide use of contact methods, they cannot principally
satisfy the demands of presentday ecological moni
toring because they fail to give the general pattern of
air pollution at vast territories with high temporal and
spatial resolutions.
Remote methods usually use optical radiation for
sensing, most of all, laser radiation[2]. These methods
are referred to as lidar (light detection and ranging)
methods. The differential absorption lidar (DIAL)
method remains the most widely used method of
atmospheric sensing [1, 2].
The aim of this paper was to study the feasibility of
using broadband femtosecond laser radiation for the
lidar sensing of the atmosphere. In this study, we the
consider radiation of a Ti:Sapphire laser, which can be
tuned in the range of 0.7–1 μm, as well as the con
verted radiation in the eyesafe spectral region 2.0–
2.1 μm.
