ABSTRACT:
A sub-nanosecond pulse operated semiconductor laser amplifier which admits light input for a time interval after the commencement of the electrical pulse. The duration of the said time interval is shorter than that of the said electrical pulse. Amplified light output reaches a peak value after the termination of the said electrical pulse. The pulsed operation can be repeated a few billion times per second. Applications in a fiber-optics communication system, a bar code scanner, and in a super speed camera are described.
