  • Laser-Line Cleanup Filters
Aug 2012
Edmund Optics Inc.Request Info
BARRINGTON, N.J., Aug. 21, 2012 — Edmund Optics has announced TechSpec OD 6 laser-line cleanup filters for use with common gas and solid-state lasers. They provide the high transmission and deep rejection necessary to isolate narrow spectral regions in a variety of applications.

The bandpass filters are fabricated using hard-coated plasma deposition technology for durability. They achieve >90% transmission at their specified design laser wavelength and offer blocking of >6 optical density at 1.5% of the laser wavelength.

With steep edges, they offer maximum transmission of stimulated emission, while eliminating noisy spontaneous emission. They can be used in laser-based fluorescence instrumentation, Raman spectroscopy, and in analytical and medical laser systems.

The filters are available with center wavelengths of 325, 355, 488, 514, 532, 632, 785, 808, 830, 980 and 1064 nm, with diameters of 12.5 and 25 mm.

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.  
spontaneous emission
Radiation emitted when a quantum mechanical system drops spontaneously from an excited level to a lower level. This radiation is emitted according to the laws of probability without regard to the simultaneous presence of similar radiation. The rate of spontaneous emission is proportional to the Einstein "A" coefficient and is inversely proportional to the radiative lifetime.
stimulated emission
Radiation similar in origin to spontaneous emission but determined by the presence of other radiation having the same frequency. Because the phase and amplitude of the stimulated wave depend on the stimulating wave, this radiation is coherent with the stimulating wave. The rate of stimulated emission is proportional to the intensity of the stimulating radiation.
