Abstract:

 The aim of this research is to design and construct asemiconductor laser range finder operating in the near infrared rangefor ranging and designation. The main part of the range finder is thetransmitter which is a semiconductor laser type GaAs of wavelength0.904 μm with a beam expander and the receiver; a silicon pindetector biased to approve the fast response time with it's collectingoptics. The transmitters pulse width was 200ns at a threshold currentof 10 Ampere and maximum operating current of 38 Ampere. Therepetition rate was set at 660Hz and the maximum operating outputpower was around 1 watt. The divergence of the beam was 0.268othe efficiency of the laser was 0.03% at a duty cycle of 1.32x10-4.Special software (ZEMAX EE 2000) was implemented for optimumoptical design.
