ABSTRACT
This article presents a dual-wavelength signal wave output system capable of generating a broad range of adjustable wavelength intervals. The setup involved the creation of a dual-wavelength cascaded Raman laser featuring composite cavities operating at 1176â
nm and 1313â
nm. Experimental investigations were carried out on an external cavity MgOPPLN-OPO driven by the cascaded Raman laser. By setting the crystal polarization period to 27.6-34.4â
µm and the temperature to 50-130°C, adjustable tunable output of dual-wavelength signal wave at 1176â
nm-MgOPPLN-OPO (1550-2294â
nm) and 1313â
nm-MgOPPLN-OPO (1768-2189â
nm) was achieved with a wavelength interval of 0-218â
nm. Under the conditions of a period of 34.4â
µm, temperature of 90°C, and an incident Raman power of 2.6 W, the highest conversion efficiency of Raman to dual-wavelength signal wave (2212, 2182â
nm) was 34.2%. Furthermore, the maximum output power of dual-wavelength signal wave was recorded at 1.02 W with an incident Raman power of 3.33 W.
