PD-LD Receives Patent for SERDS Technology

Facebook Twitter LinkedIn Email Comments
PENNINGTON, N.J., Jan. 17, 2012 — Specialty photonics packaging company PD-LD Inc. was granted US Patent No. 7,982,869, which protects the use of dual laser sources for the analysis of a single substance, the company announced.

The novel technique, based on proprietary VBG (volume Bragg grating) laser wavelength stabilization, provides the underlying mechanism for shifted excitation Raman differential spectroscopy (SERDS). SERDS is an analytical technique that the company says represents a significant development in the capabilities of Raman spectroscopy.

CEO Vladimir Ban said that the patent will allow PD-LD to offer Raman excitation sources that extend portable and lab-based instruments, and that the patent is particularly relevant to the life sciences and security industries, where fluorescence is widespread.

PD-LD’s LabSource VBG-stabilized dual laser source was announced as a finalist for the 2011 Prism Awards. (See: 2011 Prism Award Finalists Announced)

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.
