| Abstract: | A series of experiments on the interaction length between the sound and the light with Raman-Nath diffraction is reported.Then the optimum interaction length at certain sound frequency is defined.Based on those results,the devices of acoustooptic Q-switch,made of H2O or TeO2 as the medium,in terms of Raman-Nath diffraction are respectively designed.The diffraction and the loss of the devices are tested.Finally the device made of TeO2 is employed to modulate a long pulsed Nd:YAG/KTP laser.The modulated pulse... |
