Raman Source
The laser wavelength is stabilized by a volume bragg grating (VBG) to +/- 0.2 nm to render it virtually temperature independent.

With its LuxxMaster™ Raman Source PD-LD offers high quality, stable laser sources for Raman spectroscopy and other applications. This product is an enhancement of the innovative volume bragg grating, which was awarded the "Circle of Excellence” by the American Photonics Spectra magazine.
The laser wavelength is stabilized by a volume bragg grating (VBG) to ± 0.5 nm to render it virtually temperature independent (typically 0.01 nm/°C). At the same time, the FWHM value is reduced to <0.1 nm. The fiber-coupled, 785 nm laser source is equipped with a driver. The operating voltage is only 5 V and a modulation of up to 100 kHz can be achieved. The optical output power out of the 100-µm multi-mode fiber is typically 500 mW.
The laser wavelength of the 532 nm version is stabilized by a volume bragg grating (VBG) to ± 0.5 nm. At the same time, the FWHM value is reduced to < 0.1 nm.
Some of the additional features of the new laser source are its compact size and the built-in monitor diode for watching the output power. Other wavelengths are available upon request.
As an inexpensive alternative, PD-LD has introduced a OEM laser diode for spectroscopy and sensor applications. The LML-784.5T5 delivers a collimated, stabilized laser beam. The laser wavelength is stabilized with an accuracy of +/ 0.5 nm using a volume Bragg grating (VBG) and thus barely depends on the temperature anymore. At the same time, the FWHM value is reduced to < 0.5 nm.
