Abstract
This article will show an application of photon counting using an experiment with a Second Harmonic Generation (SHG) to take a look at the basics of single photon communication. This will be an opportunity to open the way for long distance single photon laser communication between unmanned robotic vehicles. This article also gives an insight into a similar, but smaller setup towards the application on unmanned robotic vehicles. In this work measurements by SHG from Si (111) sample have been done with all polarization configurations with the help of a MIRA 900 type Ti: Sapphire laser. The other part of the experiment was carried out with an SR 400 photon counter device which was used for counting the impacting pulses with the help of a photomultiplier tube (PMT).
