R2T Narrow Linewidth Diode Laser Components

R2T Diode Laser Components, are featured products of RealLight’s NL product line, which can output two wavelengths at the same time and designed for shifted excitation Raman difference spectroscopy(SERDS). With wavelength-locking technique with volume Bragging gratings (VBG) and TE cooling, they deliver stabilized power output,high Side-Mode Suppression Ratio, and low temperature dependence of the lasing wavelength.
