Paper Abstract

Tunable continuous wave (CW) green light generation between 517 nm and 538 nm at room-temperature has been demonstrated from a frequency-doubled broadly tunable quantum well (QW) external-cavity fiber-coupled diode laser by use of an uncoated periodically poled potassium titanyl phosphate (PPKTP) crystal waveguide crystal. Green light at 530 nm with maximum conversion efficiency of 14.8% and output power of 12.88 mW has been generated using a PPKTP crystal waveguide with the cross-sectional area of 3x5μm2. The possibility of tunable second harmonic generation in the PPKTP crystal waveguides with the cross-sectional areas of 4x4μm2 and 2x6μm2 was also investigated.
