Hyperspectral Absorption Sensors
Our high-energy burst-mode lasers have revolutionized ultra-fast, multi-dimensional diagnostics for dynamic and transient phenomena in both reacting and non-reacting flows. Their MOPA (master oscillator power amplifier) architecture offers flexibility in pulse shaping and frequency tuning across a broad electromagnetic spectrum. Over the past 50 years, these lasers have advanced to deliver pulse widths from 250 femtoseconds to 50 microseconds, burst durations up to 0.1 seconds, pulse energies up to 2 joules, and repetition rates up to 5 MHz. This has enabled a wide range of diagnostic techniques, including linear (e.g., laser-induced fluorescence, particle image velocimetry), nonlinear (e.g., coherent anti-Stokes Raman scattering), and multi-dimensional imaging from 2D to 4D (3D + time). Specialized features like multi-pulsing, wavelength tuning, and hybrid pulsewidths further enhance measurement capabilities. Ongoing innovations in laser design and modeling continue to expand their use in extreme environments such as hypersonics, detonations, and high-pressure combustion
Future Capabilities
Wind Tunnel Testing
Future flow measurement capabilities for wind tunnel testing are advancing with cutting-edge technologies. Optical techniques like PLIF and CARS will offer detailed flow visualization, while diagnostics like PIV and LDA will provide higher resolution and speed. High-speed imaging systems will capture fast flow dynamics, and machine learning will help analyze large datasets and predict patterns. These advancements will improve data quality and support better aerospace designs. Spectral Energies is at the forefront of these innovations, leveraging their expertise in high-speed laser diagnostics and advanced imaging systems to enhance flow measurement capabilities.
