Femtosecond Laser System for Biological Mass Spectrometry

Executive SummaryMass spectrometry is a key analytical tool for analyzing proteins and metabolites. Typically, complex protein mixtures or individual proteins are processed and then introduced to the mass spectrometer. Peptide sequence information is obtained via subjecting individual ions to fragmentation. Protein identification is achieved by database...

Fast Laser Amplification System

Executive SummaryIt is often desirable to provide amplification of peak intensity in ultrafast laser systems. It is known in the art to employ chirp pulse amplification for these lasers. Chirping overcomes concerns with intense ultrashort laser pulses inducing nonlinear optical processes in transparent media which would otherwise damage the amplification...

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...

Non-invasive biomedical imaging

IntroductionThere has been an increasing need for more effective ways in diagnosing cancer. Current, technologies are widely available for fluorescently labeling tumors; however, UV and visible light cannot penetrate living tissue. In addition, during a surgery there is a need for ensuring that the entire tumor has been removed with clean margins and...

Materials with Optically-Addressable Compression Memory

IntroductionThere is a need for recording compressive incidents in areas such as head injuries, or packaging. Concussion prevention and increased head protection for athletes has become a focus in all levels of sport. Football is one sport in particular that has recently come under fire for the many head injuries sustained by athletes, and their possible...

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...
