Overview of remote sensing laser development and semiconductor laser technology
There are many new requirements for remote detection in the atmosphere that have been generated by government agencies. The associated field scenarios anticipated for carrying out the measurements, in many cases, are extremely demanding on the existing technology. Moreover, additional innovations in remote-sensing technology will be needed to satisfy requirements for longer measurement ranges, detection of low concentration levels of target species, new laser wavelengths for a growing list of species, and compact/efficient systems for deployment in airborne platforms. Remote-sensing laser transmitter architectures based on diode-pumped, solid-state lasers offer the most promise in terms of meeting these demanding requirements, although in order to realize this promise, the present level of power performance must be extended by one to two orders of magnitude. The LLNL remote sensing laser development program is aimed at developing those necessary solid-state laser systems with performance characteristics that go well beyond the state-of-the-art. This paper will cover: (1) an overview of the remote sensing laser development program, which includes high-average power solid-state lasers, tunable laser/OPO systems, temperature-insensitive nonlinear materials, and new solid-state/semiconductor laser materials; and (2) a review of the technical progress on semiconductor laser technology development.
