Dual Wavelength Laser Diode — 784.5/785.5 nm, 785/1064 nm

SKU: DWLD

The DWLD is a high-power, narrow-linewidth, multimode laser diode that uniquely provides two grating-locked wavelengths simultaneously. Designed specifically for shifted excitation Raman difference spectroscopy (SERDS), it offers a compact and integrated solution for Raman spectroscopy applications. Featuring wavelength-locking technology based on volume Bragg gratings (VBGs) and thermoelectric (TE) cooling, the DWLD delivers stable optical power, a high side-mode suppression ratio (SMSR), and low temperature dependence of the lasing wavelengths. The laser diode is coupled to a 105/125 µm fiber for convenient optical delivery. A dedicated laser diode driver is also available, providing a compact and compatible drive solution for the DWLD.
