| Popis: | A high repetition rate electro-optical-Q-switched intracavity optical parametric oscillator (IOPO) is realized by using two RbTiOPO4 (RTP) crystals as electro-optic (EO) modulator. Three repetitions of the EO modulator ( f p = 15, 20, and 30 kHz) were applied in the experiment. The pulse width can be minimized to 7ns when the input energy is 24.4 J at three modulating repetitions. The peak power of the signal light increases with reducing the pulse repetition rate. By considering the gradual loss from the delayed switched time of the EO switch, the coupled rate equations of IOPO under the assumption of the uniform distributions of the intracavity photon densities are given and the numerical solution of the equations fits the experimental data well. |
