High-Resolution Microscopy: Developing Laser Optics for 3D Imaging

Fine venules, thin branches of nerve tracts - thanks to the ultramicroscope developed at the Bioelectronics Department of the Institute for Solid-State Electronics at the Vienna University of Technology, the tiniest details of biological tissues can be represented in 3D.

Cobolt Zouk 355 nm 20mW: High Performance, Single Frequency DPSS Laser
Dec. 11, 2012

Cobolt Zouk 355 nm 20mW: High Performance, Single Frequency DPSS Laser

The Cobolt Zouk is a continuous-wave (CW) single-frequency DPSS laser operating at 355 nm in a perfect quality TEM00 beam (M2<1.1) and with 10 or 20 mW output power.
A proprietary laser cavity design provides ultra-low noise performance of typically <0.2% rms (over 20 Hz-20MHz and over 10-40ºC), a narrow spectral linewidth of <1MHz and immunity to optical feedback. more

Construction of Compact X-ray Lasers at Ultra-short Wavelengths

To look at small objects typically requires big machines. For example, the study of single atoms with a laser requires x-ray radiation of such high energy that it is only produced by accelerating electrons in large facilities. Researchers at the Riken SPring-8 Center in Harima have developed a more affordable electron laser design, the SPring-8 Angstrom Compact free-electron Laser (SACLA), which is not only compact and therefore economic to build but also delivers x-rays with unprecedented short wavelengths. Results were published in Nature Photonics.

Profiling X-ray Free-electron Laser Pulses

With their ultra short X-ray flashes, free-electron lasers offer the opportunity to film chemical reactions or atoms in motion. However, for this super slow motion the arrival time and the temporal profile of the pulses must be precisely known. An international team of scientists has now developed a measurement technique that provides complete temporal characterization of individual FEL (free-electron laser) pulses at DESY´s soft-X-ray free-electron laser FLASH. more

Craic Apollo: Now Offered with Peak Wavelengths Lasers

Craic Technologies has announced the addition of lasers with peak wavelengths ranging from 405 nm through the 830 nm to the Craic Apollo Raman microspectrometer.
Craic Apollo enables scientists and engineers to measure the Raman spectra from microscopic samples or microscope sampling areas of large samples. The microspectrometer can even be added to a microspectrophotometer adding Raman microspectroscopy to UV-visible-NIR absorbance, reflectance and fluorescence microspectroscopy and imaging. more
