Dual Electrode Teaco <sub> 2 </ Sub> Laser Pulse Polarization Encoding And Decoding

In this paper, the characteristics of the double-electrode-pair laser has been systemically studied. It has high increment and power of output, especially it can produce two pulses of high power with adjustable time interval on a common vacuum condition. Applying photoelectric Packels box of GaAs to encode double pulses beam of polarized light, the coding system produces left-handed or right-handed polarized light by turn, basis on which the decoding system of double beam of light is designed. By using microchip ,a real time and high speed receiver is designed at the data processing. The system has significant value of theory and practice at the object recognition , polarization control,atmosphere supervising , laser cooling atom etc.
