Abstract :
An infrared optical parametric oscillator using potassium titanyl phosphate (KTP) pumped by a 1.06- mu m Nd:YAG laser is discussed. Oscillation was obtained around the degenerate wavelength at 2.12 mu m with a pump threshold of 40 MW/cm/sup 2/ in a 30-ns pulse. Difference frequency generation with an output at 2.4 mu m was also obtained between inputs at 1.06 and 1.9 mu m. The broad tuning range and high damage resistance of KTP make this an important new source of tunable infrared radiation.<>
