This report details the concept and experimentation concerned with the study of glass fiber lasers as possible elements for use in optical digital data processing. Evidence is presented of amplification as large as 5 x 10 to the 4th power of low level signals by a one meter fiber laser. Saturated amplification, as a result of a high input signal, in a fiber laser is demonstrated and studies of parameters affecting refractory behavior are discussed. Properties of one, five and ten meter long fiber lasers are set down. Methods derived for prevention of oscillation in fiber lasers are described. Optical coupling between two fiber lasers in a common cladding is demonstrated and related to interconnection of fiber laser elements. Laser quenching experiments are presented and analysis is made of the laser quenching effect. Europium doped glass is discussed as an excited state absorber at 1.06 microns, possible neuristor materials are catalogued and a Q-switched laser for generating multiple pulses is described. Author
