{"project":{"acronym":"","projectId":93414,"title":"Compact 2-Micron Transmitter for Remote Sensing Applications","startTrl":3,"currentTrl":4,"endTrl":4,"benefits":"Potential NASA applications of the proposed compact single-frequency 2-micron laser transmitter include airborne demonstration systems for 3D winds and ASCENDS atmospheric CO2 measurement missions, as well as other NASA atmospheric spectroscopy efforts focused on the SWIR spectral region. The compact pulse-stretched transmitter developed in Phase II will match the wind measurement potential of the current NASA DAWN wind lidar operating at 100 mJ and 10 Hz, but in a much smaller and more reliable package. The fully-functional high-power SWIFT cw laser delivered at the end of Phase I will be immediately applicable to several 2.05 um NASA remote-sensing programs, and will be available as a product from BP soon after completion of the initial Phase I effort; similarly, the \"nano-SWIFT\" will reach product maturity by the end of Phase II. The innovations developed in this Phase I effort can inform ongoing and future NASA remote sensing programs, including 3D Winds, ASCENDS CO2 remote spectroscopy, and other programs requiring very compact, robust 2-micron lasers and associated photonic technology. We also see this technology benefitting systems for identifying and tracking orbital space debris and other hazards from space.
Non-NASA applications of the proposed single-frequency 2-micron long-pulse, Fourier-transform-limited Q-switched transmitter laser technologies begun in Phase I and further matured in Phase II include eye-safe wind energy management lidar (winds forecasting, wind farm energy extraction optimization, and gust-front prediction), aircraft wakes detection and analysis, drone-based remote sensing applications, greenhouse gas flux remote spectroscopy, and numerous Doppler winds applications. As noted above, the high-power and compacted SWIFT cw master oscillator sources would be made available commercially for numerous remotes sensing and spectroscopic applications. Actively pulse-stretched laser technology has potentially quite broad application across many commercial, industrial, scientific, and research fields, where very robust, very compact transform-limited laser energy is required; no commercially-available such lasers exist on the market at present.","description":"In this Phase II effort we propose to work with NASA to extend the Phase I achievements, which focused on design and development of very compact master and long-pulse slave oscillator lasers operating near 2.05 um wavelength. Beyond Photonics LLC's \"SWIFT\" laser was matured and largely productized, with an initial unit delivered in Phase I. In parallel, conceptual and preliminary design and risk-reduction of a very compact short-cavity Tm,Ho:YLF Q-switched laser was achieved, which will be extended significantly in Phase II and result in a robust injection-seeded, actively pulse-stretched prototype. The compact transmitter will include a \"nano-SWIFT\" that will have size and weight comparable to a butterfly-packaged DFB diode laser but with far better frequency stability and higher power. In Phase II we will demonstrate output characteristics of 32 mJ, 100 Hz PRF, and 300-500 ns pulse durations from this compact robust injection-seeded transmitter. This moderate-PRF moderate-energy transmitter will be immediately suitable for 3D winds from ground and airborne platforms and with continued TRL advancement eventually space platforms. The transmitter will be capable of efficient operation at >4 W average power at lower pulse energies and higher PRFs (e.g.. 1 -4 kHz) which is suitable for IPDA spectroscopy and hard target measurement lidar systems operating from space (following an appropriate engineering and qualification effort) using either coherent or direct detection with state-of-the-art low-noise direct detectors. The overarching objective of the proposed effort is to develop compact, efficient, and reliable pulsed and cw lasers and lidar transmitters for future NASA missions. Specifically, we address needs described for 3D winds, atmospheric CO2 and H20 concentration sensing in the 2.05 um region; but we also recognize that such innovations can be readily applied to transmitter laser operation at other IR and SWIR wavelengths and associated instruments.","startYear":2017,"startMonth":3,"endYear":2020,"endMonth":10,"statusDescription":"Completed","principalInvestigators":[{"contactId":420712,"canUserEdit":false,"firstName":"Sammy","lastName":"Henderson","fullName":"Sammy

Applications","startTrl":3,"currentTrl":4,"endTrl":4,"benefits":"Moderate average power, compact, operationally flexible 2 ?m solid-state/fiber hybrid transmitter laser solutions will tangibly and positively impact the readiness of current and future NASA laser remote sensing systems and missions for airborne and in the case of atmospheric DIAL instruments, space-based measurement applications. Full development, test, and delivery at the end of Phase I of BP?s extremely compact and ruggedized master oscillator source will directly benefit existing NASA programs operating at 2 ?m and will accelerate commercial availability. Efficient single-frequency pulsed 2 ?m wavelength lasers with variable pulse duration and PRF will greatly enhance the technical readiness of 2-micron wavelength coherent- and direct-detection lidar systems for ASCENDS type missions, IPDA, LAS, and hard-target identification, tracking, and imaging. Many of the innovations proposed can be transferred to other relevant laser gain media and wavelengths for other NASA applications.
Non-NASA commercial applications of the proposed pulsed 2-micron solid-state/fiber hybrid laser sources include DoD hard target and space debris tracking and imaging problems as well as research and industrial applications requiring very compact efficient front-end transmitter lasers in the eye-safe SWIR wavelength region. Specifically relevant to Beyond Photonics, we will capitalize on past NASA SBIR innovations that produced our initial SWIFT single-frequency solid-state cw single-frequency laser format and apply them to the pulsed single-frequency (injection seeded) transmitter laser design proposed here; we plan to incorporate new design concepts in this master oscillator (MO) laser, and then build, test, and deliver a fully functional prototype of the new MO source in Phase I. We ultimately envision commercial development of a small, rugged, and compact differential-absorption lidar (DIAL) sensor product for airborne measurement of CO2 and water vapor concentrations in the atmosphere, and other similar laser remote sensing applications.","description":"Beyond Photonics proposes to develop a highly compact, efficient next-generation single-frequency pulsed transmitter laser for current and future NASA missions focused on laser remote sensing in the short-wave infrared wavelength region near two microns. More reliable and compact sources of this type are required for NASA and commercial/military applications such as terrestrial and airborne Doppler winds, long-range measurement of molecular CO2 and H2O concentrations in the atmosphere, and identification and tracking of fast moving hard targets (e.g. space debris, asteroids, docking). We will emphasize the use of small but powerful lasers operating near 2 ?m and capitalize optimally on solid-state laser designs recently developed at Beyond Photonics as well as our team?s extensive past experience with this specific laser technology. Efficient, compact hybrid approaches using bulk solid-state pulsed transmitters followed by doped-fiber amplification will be a focus to reach flexible performance on the order of 200 ?J/pulse, 0.5-8 kHz PRF, which can serve as an effective transmitter for many applications as-is in both coherent or direct detection lidar architectures, or which can be increased via further amplification as needed. Operationally flexible Q-switched and injection seeded operation compatible with several different applications with differing requirements will be emphasized. Very compact efficient MO laser technology will also be exploited and a prototype MO delivered in Phase I. Techniques will be explored to increase output pulse duration to narrow the transform-limited pulse spectra while maintaining very compact laser cavity length. These innovations will apply directly to current NASA missions and instruments (Doppler lidar, IPDA, LAS) and accelerate commercial development and availability of practical ground-based and airborne systems (e.g. compact airborne CO2 concentration-measuring instruments) at BP and elsewhere.","startYear":2016,"startMonth":6,"endYear":2016,"endMonth":12,"statusDescription":"Completed","website":"","program":{"acronym":"SBIR/STTR","active":true,"description":"
