The high power lasers that make up these laboratories provide a unique high-temperature testing capability wherein materials are exposed under a variety of temperature and stress conditions. The facilities include 1.5 kW and 3.0 kW (wavelength 10.6 microns) CO2 lasers, pyrometry and thermography temperature measurement instruments and state-of-the-art data acquisition and control systems.
Laser beam optic systems are incorporated in the rig designs to achieve various laser beam configurations and energy distributions. These tests provide near-realistic transient and steady-state temperature and thermal gradients encountered in advanced engine systems, including simulation of aircraft, diesel and space propulsion engine conditions.
