Carbon nanotubes are expected to be used in a myriad of applications ranging from military protective clothing to hydrogen storage. Due to their nanometer dimensions, however, the structure and surface chemistry of individual carbon nanotubes cannot be easily studied using conventional techniques. Norihiko Hayazawa and colleagues from the Near Field NanoPhotonics Research Team at the RIKEN Center for Advanced Photonics have now developed a high-resolution microscopy technique that can resolve individual carbon nanotubes under ambient conditions. The work has been published in Nature Communications.

Toptica´s TopMode is a high-coherence, high-power diode laser which operates as easily as a HeNe-laser.
The proprietary CoHerence-Advanced Regulation Method (CHARM) provides active stabilization of the lasers' coherence and ensures continuous single-frequency operation for excellent stability of lasing wavelength and output power. Featuring a spectral width of less than 5 MHz (a coherence length greater than 20 m), the TopMode is available at six wavelengths from 405 nm to 685 nm.

Using carbon nanotubes, a research team led by Professor Hyung Gyu Park in collaboration with Dr. Tiziana Bond has developed a sensor that greatly amplifies the sensitivity of commonly used but typically weak vibrational spectroscopic methods, such as Raman spectroscopy. This type of sensor makes it possible to detect molecules present in the tiniest of concentrations.

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.

Using an enhanced form of "chemical microscopy" developed at the National Institute of Standards and Technology (NIST), researchers there have shown that they can peer into the structure of blended polymers, resolving details of the molecular arrangement at sub-micrometer levels. The capability has important implications for the design of industrially important polymers like the polyethylene blends used to repair aging waterlines.
