Abstract:

Requirements for a sensitive, accurate sensor for applications in space-based strategic defense and target recognition point to the need for the development of very robust, agile coherent laser radar instruments. Recent advanced in high power pulsed and continuous-wave CW laser diode adn diode array technology has prompted a renaissance in the use of solid-state laser transmitters in coherent and incoherent laser radar systems. In particular, all- diode-pumped coherent laser radar systems now appear feasible for ground-, air-, and space-based applications where electrical power efficiency, size, and weight considerations are very important. The unattended lifetime, pulse repetition frequency PRF, and beam quality of such an all-solid-state laser radar are expected to be improved upon over both CO2 and flashlamp-pumped solid- state systems. In most applications where atmospheric turbulence is not too serve, the performance of the shorter wavelength all-solid-state laser radar systems exceeds that of the longer wavelength CO2 systems.
