Integrated Sensor System for Load and Condition Assessment

Not Available This Phase I SBIR program will develop an ultraviolet (UV) source, specifically a diode-pumped solid-state laser which produces 1W power in a continuous-wave (CW) format tunable in the spectral range 300-350 nm. We will use a cw mode-locked laser at 1 micron as the pump source for a cascaded optical parametric oscillator and sum-frequency generator, followed by a second harmonic output stage. The technology advances that make this innovation possible are high power diode pumps and solid state laser architectures, passive semiconductor saturable absorber modelockers, and efficient microstructured nonlinear materials. Compared to current systems, this all-solid-state device will offer lower operating costs through increased reliability, higher efficiency, and longer lifetime, and better performance through high power, diffraction-limited beam quality, and wavelength selection capability
