Dual Spectrum Stabilized Fiber-Coupled Raman Laser Source
The DSFL 785 nm Spectrum Stabilized Fiber Coupled Laser Source outputs powerful and extremely stable dual wavelength lasers through a single fiber output connector that is ideal for Shifted Excitation Raman Difference Spectroscopy (SERDS), a method that effectively reduces the fluorescence interference in Raman Spectroscopy. The unit contains two fiber-coupled high-power diodes that are spectrally narrowed and wavelength-stabilized by incorporating a Volume Bragg Grating (VGB). It outputs over 300 mW and 500mW at both 784.5 nm and 785.5nm wavelengths, having wavelength stabilization within 0.5 nm. This laser source contains a unique high-power fiber-optic switch with an internal beam dump, which permits rapid on-and-off switching between the two wavelengths while ensuring that no laser emission emerges from the FC/PC connector output port in between measurements.
