INDUSTRIAL LASER PULSE METROLOGY

VAlue proposition The present technology is a method and apparatus for measuring the performance of industrial ultrashort‑pulse, diode‑pumped lasers. While these lasers are widely used in high‑power, high‑repetition‑rate applications, users have observed that systems with identical published specifications often deliver very different processing...

MILLI-RADIAN ULTRAFAST LASER PULSE METROLOGY

VAlue proposition Ultrashort laser pulses have seen widespread use in scientific, medical, and industrial fields. Their degree of coherence is a key feature that dictates the accuracy and amount of noise in its applications. The relative spectral phase within the bandwidth of the pulse needs external methods to measure and control. Controlling the...

Laser for Fluid Dynamics

Executive SummaryOne of the hallmarks of turbulence is the formation of rotating currents known as vortices. Measuring the vorticity is of great importance in fluid dynamics, especially for aerodynamic design and control of air flight. MSU researchers have developed a novel high precision technology to permit the use of a laser for direct measurement...

Ultrafast Square Pulses

Executive SummaryIt is desirable in many applications to precisely control the output pulse shape for high speed and high power laser systems. A flat top, fist rise and fast fall pulse is a desired pulse shape. In the case of a bandwidth-limited Gaussian pulse, the peak of the pulse is near the threshold but the rest of the pulse is well below the...

Laser for Standoff Detection

IntroductionStandoff detection is used to identify specific, usually hazardous, materials at a distance. Hazardous materials may be of an explosive, chemical, biological, or nuclear nature, and so mitigating a potential threat is extremely important. The global market for hazard monitoring equipment has grown significantly in recent years and this growth...
