Abstract

This paper is to introduce the principle and the experimental operation of Q-switching and tuning of flashlamp pumped Ti:Sapphire laser with electro-optic crystal. A LiNbO₃ (LN) crystal (13.8 X 14.7 X 46.5 mm³), a quartz quarter wave plate (204 micrometer in thickness), and a Glan prism were inserted in the cavity. Before a Q-switching voltage was applied to the LN crystal, the loss corresponding to quite wide wavelength band was high, the oscillation of the laser was prevented. The Q switching was achieved with the voltage on, different voltage corresponding to different wavelength at which the laser had the highest Q figure. The Q- switching and the tuning of the laser was achieved at the same time in this way.
