摘要： In a laser apparatus, when no voltage is applied to optical modulator, a first linearly polarized component of a laser beam which passes through a polarization control mirror causes a laser oscillation in a first laser resonator and a laser beam is output from a second reflecting mirror. When a pulsed voltage is applied to the optical modulator, a second linearly polarized component of the laser beam reflected by the polarization control mirror passes through the optical modulation means and causes a Q-switched laser oscillation in a second laser resonator. In this case, the first linearly polarized component passes through the polarization control mirror and is output from the second reflecting mirror. This technique makes it possible to combine a Q-switched laser apparatus with a non-Q-switched laser apparatus without causing the power of the laser beam to exceed a maximum allowable limit that an electrooptical modulator can handle.
