Lasers for Raman Spectroscopy
FUZHOU, FUJIAN, China, Oct. 2, 2009 – Photop Technologies Inc. has announced its Narrow-Linewidth Lasers (NLLs) for Raman Spectroscopy applications. Photop_RamanLaser.jpg

Based on proprietary advanced technologies, the NLL series features significant reduction of the spectral bandwidth, one of the key factors for Raman spectroscopy applications. A built-in temperature controller produces good power stability with variation of <±2% over the long term.

The lasers are available in wavelengths of 532, 785 and 1064 nm and in multimode fiber-coupled or free-space versions. Customized fibers are optional.

Other applications include medical, military and sensing.

The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
Raman spectroscopy
That branch of spectroscopy concerned with Raman spectra and used to provide a means of studying pure rotational, pure vibrational and rotation-vibration energy changes in the ground level of molecules. Raman spectroscopy is dependent on the collision of incident light quanta with the molecule, inducing the molecule to undergo the change.
