Paper Abstract

Two versions of the singly resonant parametric oscillator (OPO) are investi- gated, synchronously pumped by microsecond pulse trains of a feedback controlled Nd:glass laser. The first setup utilizing a LiNbO crystal generates narrow-band, sub-ps pulses with tuning range 1 .35 - 2. 1 1 pm and 5 % conversion efficiency. The second OPO-system applies a BBO specimen and a novel double pass pump geometry with partial group delay compensation. Broadly tunable pulses are generated in the wavelength range 0.7 - 1.8 pm with duration between 160 and 260 fs and energy conversion of 3 %. Steep pulse wings are observed with l/e decay time of 90 fs. Under special conditions parametric pulses as short as 65 7 fs are obtained.
