Spiral fringes show that the generated beams possess a well defined single OAM and usually used in the literature as an indicator of its purity. However, this cannot be used to measure quantitatively the purity of the generated OAM. To evaluate the optical intensity suppression ratio I−/I+ ...
Advances in real-time multispectral optoacoustic imaging and its applications. Nat. Photonics 9, 219–227 (2015). 19. Shi, J. et al. High-resolution, high-contrast mid-infrared imaging of fresh biological samples with ultraviolet-localized photoacoustic microscopy. Nat. Photonics 13, 609–615 (...
While innovative, this first-generation technique requires sub-nanometer alignment of its internal optics, which translates directly into limitations in terms of high cost, reliability, and vulnerability to vibrations and temperature/pressure changes. To overcome these drawbacks, our scientists developed, ...
Laser Beam Shaping Using Hollow Optical Fiber and Its Application in Laser Induced Thermal Printing A Gaussian beam of single mode fiber laser was changed into a ring-shaped pattern after it was transmitted through the hollow optical fiber. The ring-shape... J Yi,K Lee,I Park,... - 《Jou...
The time consuming process of LCM may elicit ribonucleic acid (RNA) degradation, which may extend dramati- cally depending upon manipulations and tissue type. Notably, intestinal tissues are known to maintain the poorest RNA integrity with fast degradation, hampering the downstream applications such ...
Strong terahertz (THz) electric and magnetic transients open up new horizons in science and applications. We review the most promising way of achieving sub-cycle THz pulses with extreme field strengths. During the nonlinear propagation of two-color mid-infrared and far-infrared ultrashort laser pul...
