| Abstract: | In this paper, a compact green and near-infrared two-color continuous wave laser source with emission wavelengths at 516 nm and 775 nm are demonstrated, respectively. A cascaded periodically poled Mg doped lithium niobate crystal is designed and fabricated for simultaneous conversion of second harmonic generation(SHG) and third harmonic generation(THG) of communication wavelength, the output of green and near-infrared laser can be obtained at the same temperature. By set up a single pass laser measurement system, 0.15 mW green light at 516 nm and 1.19 mW light at 775 nm are obtained with 2 W pump power and the crystal temperature is controlled at 30.8 ℃. The experimental results will provide an important case for compact dual wavelength collinear laser which pumped by a single laser. |
