Abstract

Due to present importance of laser range-finders and their applications several
industrial, medical and military applications, especially range finding, require the
use of long life sealed off mini-TEA-CO₂ laser systems operating at (10.6 μm)
Designing and constructing such systems and represents the main aim of this
work
The Laser range finder includes TEA-CO₂ system as laser transmitter with
interactive cavity with (130*20*6) mm dimensions, maximum out put energy
(70mJ) with plus duration (120nsec) and frequency (1Hz). A photo conductive
(He Cd Te) detector was used to detect the transmitted and received pulse The
device is used as received system and supplied with objective lens (30mm)
diameter. Due to the mobilization requirements, the laser system was sealed using
solid catalyst. The maximum range measured is (15km).
