New type of chemical laser utilizing electronic transitions with a chain excitation mechanism

Abstract

An improved data transmission scheme that can be used for any chosen transmitting direction in free space is introduced. This scheme is obtained by analyzing the analytic form of the diffracted spectrum of a coherent broad band Gaussian spectrum incident on an adjustable tilting circular mirror. It is found that the transmitting angle and tilting angle are conjugate. The advantages of this method are that the transmission direction can be selected arbitrarily in advance and that it is easy to implement compared with other previous schemes which modulate some properties of the light source. #
