Abstract

We have investigated second-harmonic generation in short- period periodically-poled bulk and waveguide potassium titanyl phosphate crystals to generate blue light using subpicosecond laser pulses. For the bulk, the maximum conversion efficiency is approximately equals 5.5%, which is about two orders of magnitude larger than that achieved previously. For the waveguide, the maximum conversion efficiency is approximately equals 32%, which is about a factor of 4 higher than that obtained before. These measured values are in good agreement with our theoretical results. We have observed saturation of conversion efficiency, which sets a limit to the maximum conversion efficiency that can be obtained.
