Applied Optics welcomes submissions to a feature issue on "Laser Applications to Chemical, Security and Environmental Analysis (LACSEA)" in conjunction with the 2018 LACSEA Conference at the Imaging and Applied Optics Congress in Orlando, Florida, on 25-28 June 2018. Submissions of related papers that were not part of the 2018 LACSEA Conference also will be considered.
The further development of lasers and laser systems drives applications in optical sensing and analysis in various fields in industry, military, security, medicine, and chemistry. For analytical purposes in the field, laser sources need to be compact, rugged, tunable in wavelength, and of suitable power to provide data of sufficient quality for temperature, species composition, and velocity. Another consideration in laser-based analytical measurements is the speed with which data can be collected, which is limited—besides constraints in detector electronics—by the repetition rate and wavelength flexibility (if required) of the employed laser systems. Considerable progress has been made in recent years in high-repetition-rate pulsed laser systems with pulse energies in the hundreds of millijoule range that enable new approaches for temporally resolved measurements, even for methods with inherently low signal intensity.
This special issue is aimed at scientists, engineers, and practitioners interested in understanding the basic principles and diagnostic purposes of a variety of laser-based methods designed for the quantitative detection and monitoring of essential parameters in probed samples of different origin and aggregate state (i.e., gas, liquid, or solid). Its intent is to bring together the development areas of the necessary equipment (lasers, detectors, optics) as well as the methods themselves, and new approaches. The emphasis should be on applications of methods; however, theoretical discussion of both methods and data evaluation is also invited. The methods discussed in this feature issue must meet the requirement of being spectrally selective and provide sufficient detection sensitivity to optimize the performance for the application. There are numerous disciplines that are involved in the successful development of the various diagnostic methods. These include light sources and optical instrumentation, computational algorithms, and spectroscopy. They all contribute to defining the technique and its applications.
Topics of interest include, but are not limited to, the following areas:
All papers need to present original, previously unpublished work and will be subject to the normal standards and peer review processes of the journal. The standard Applied Optics publication charges will apply to all published articles. To be eligible for publication, an expanded conference paper needs to add substantial and/or significant new information to the original conference summary. Please see OSA's guidelines on expanded conference papers for details.
Manuscripts must be prepared according to the usual standards for submission to Applied Optics and must be uploaded through OSA's electronic submission system, specifying from the drop-down menu that the manuscript is for the Feature Issue on LACSEA 2018.
