PD-LD Introduces Raman Sources at 532 nm
Pennington, N.J. (April 10, 2008) – PD-LD, Inc., the worldwide leader in Volume Bragg Grating® (VBG®) technology, has announced the debut of a new Raman laser source product that operates in the visible spectrum at 532nm. The innovative device bolsters PD-LD’s already popular LuxxMaster® Raman Boxx™ product line and offers customers an excellent high power laser source at an economical price.
Like previous Raman spectrometers that operate in the 785nm infrared range, PD-LD’s new green Raman source offers a narrow line-width, high power, compact and a rugged design making it particularly suitable for portable instrument applications. The device’s small size and simple interface makes it ideal for industrial, military and security applications.
“This is a breakthrough solution for companies that rely on hand-held Raman spectrometers,” said Neal Stoker, PD-LD Director of Marketing. “PD-LD is equally excited to announce plans to roll out a 14-pin butterfly version beginning in the third quarter.”
The fibre-coupled device provides 50mW, relying on PD-LD’s patented VBG-stabilised 808nm laser to pump a YAG crystal that has been frequency doubled to 532nm. This exclusive PD-LD design helps the laser achieve higher stability in a narrow linewidth.
“We believe that our new 532nm source addresses needs of many Raman spectrometer manufacturers. This is yet another demonstration of the application of the VBG technology, developed by our world-class engineering team” said Dr. Vladimir Ban, PD-LD President and CEO.
Raman spectroscopy is an ideal tool for chemical analysis due to its advantages over other analytical techniques. Since it is a non-destructive and non-contacting method of obtaining the unique spectrum of materials, requiring no sample preparation, it is particularly beneficial for Homeland defence applications. Typically, the laser source is the most expensive part of the system, but PD-LD’s new green Raman offering couples VBG and LuxxMaster Raman Boxx technologies to provide an economical solution that delivers a smaller, more stable light source with a spectral bandwidth of less than 3 wave numbers.
