High-Efficiency, Single-Frequency Laser and Modulator Study
Abstract
The work described in this report is the final year's effort of a three-year program to study wide bandwidth laser communications at 1.06- micrometer wavelengths. The detailed objectives of this study program are as follows: (1) Design a laboratory communication system, using 1.06-micrometer radiation from a Nd:YAG laser and having a system bandwidth of 2 to 4 GHz; (2) Assess the state-of-the-art of high-frequency photodetectors, with emphasis on a cross-field photomultiplier tube (PMT), that offer good frequency and spectral response and are suitable as the receiver elements of this communication demonstration; (3) Define and design the necessary microwave, digital-modulation and frequency-modulation subsystems for the communication system; (4) Assembly and operate the various subsystem; and (5) Demonstrate and evaluate the system performance in a laboratory environment. During this quarter, objectives (1), (2) and (3) have basically been accomplished.
