“…Compared with DLs and QCLs in the MIR region, ICLs are quite attractive for tunable laser absorption spectroscopy (TLAS) applications owing to their availability throughout the entire spectral region, as well as the low drive powers they require [15,16]. Therefore, ICLs serve as very elegant solutions in combustion, petrochemical, and biochemical sensing applications [17][18][19]. Furthermore, CH 4 , HCl, HBr, CO, CO 2 , NO, and H 2 O can be detected with particularly high sensitivity in this wavelength regime, since the detection sensitivity typically increases at long wavelengths.…”

“…The technique was originally based on lead-salt diode laser sources emitting in the Mid-InfraRed (MIR), and subsequently adopted solid-state semiconductor sources [69]. The emergence in more recent times of Quantum Cascade Lasers (QCL) with operational wavelengths ranging between 2.6 mm to beyond 300 mm is having substantial impacts on TLAS [56,[69][70][71][72][73], and several QCL-based TLAS applications are emerging [74][75][76][77][78][79]. Single-Particle Light Scattering was also implemented in airborne platforms to measure size distribution of cloud droplets and ice crystals between 1-50 mm [80].…”

a b s t r a c tThe underlying principles and technologies enabling the design and operation of airborne laser sensors are introduced and a detailed review of state-of-the-art avionic systems for civil and military applications is presented. Airborne lasers including Light Detection and Ranging (LIDAR), Laser Range Finders (LRF), and Laser Weapon Systems (LWS) are extensively used today and new promising technologies are being explored. Most laser systems are active devices that operate in a manner very similar to microwave radars but at much higher frequencies (e.g., LIDAR and LRF). Other devices (e.g., laser target designators and beam-riders) are used to precisely direct Laser Guided Weapons (LGW) against ground targets. The integration of both functions is often encountered in modern military avionics navigation-attack systems. The beneficial effects of airborne lasers including the use of smaller components and remarkable angular resolution have resulted in a host of manned and unmanned aircraft applications. On the other hand, laser sensors performance are much more sensitive to the vagaries of the atmosphere and are thus generally restricted to shorter ranges than microwave systems. Hence it is of paramount importance to analyse the performance of laser sensors and systems in various weather and environmental conditions. Additionally, it is important to define airborne laser safety criteria, since several systems currently in service operate in the near infrared with considerable risk for the naked human eye. Therefore, appropriate methods for predicting and evaluating the performance of infrared laser sensors/systems are presented, taking into account laser safety issues. For aircraft experimental activities with laser systems, it is essential to define test requirements taking into account the specific conditions for operational employment of the systems in the intended scenarios and to verify the performance in realistic environments at the test ranges. To support the development of such requirements, useful guidelines are provided for test and evaluation of airborne laser systems including laboratory, ground and flight test activities.

Laser absorption spectroscopy (LAS) has been rapidly developed and widely applied to combustion diagnosis in recent decades. As a costeffective tool for measuring multiple combustion parameters, LAS provides unique properties in terms of accuracy and sensitivity for understanding the reactions and kinetics in reactive flows. Line-ofsight and tomographic LAS techniques have stimulated numerous applications and been proved to be robust for in situ combustion diagnosis in uniform and non-uniform combustion fields, respectively. This review highlights the breakthroughs in the evolution of LAS techniques from the viewpoints of key principles, sensors and instrumentations developed for combustion diagnosis, with particular emphasis on a series of spatially-resolved LAS techniques with their recent applications on obtaining high-fidelity measurement results with minimal intrusion to the practical combustors. Along the way, we note some challenges and requirements for further development of the LAS-based combustion diagnosis.
