We have developed an advanced design for a dual-wavelength laser source used in Coherent Anti-Stokes Raman scattering (CARS) microscopy and Stimulated Raman Spectroscopy (SRS) addressing a wider frequency range for bio-imaging, spanning from <630cm^-1 to 2250cm^-1, while maintaining a fast tuning time of a few seconds across the entire range. Furthermore, we have achieved improved tunability of the Stokes and pump power, allowing for versatile applications. The system supports repetition rates of up to 10MHz, and the spectral width of the signals is narrow (<15cm^-1), enabling a wide range of potential uses.
