Abstract
We present the first demonstration of using the second harmonic generation effect to upconvert dissipative soliton resonance laser pulses. We have designed and built two independent dissipative soliton resonance lasers, emitting rectangular shaped, nanosecond pulses in the 1.06 µm and 1.56 µm wavelength regime, respectively. Periodically poled lithium niobate crystals with appropriate periods were used as the nonlinear medium. Dissipative soliton resonance pulses with central wavelengths of 532 nm and 780 nm and pulse energies of 0.15 µJ and 0.02 µJ were generated as the result of the second harmonic generation effects. Conversion efficiencies of 30% and 4% were obtained for conversion of 1.06 µm
and 1.56 µm pulses, respectively.
