Abstract

Laser apparatus with an electro-optic Q-switch assembly comprises a lasing medium which produces an unpolarized light beam when pumped, a polarizing beam splitter dividing the unpolarized beam into two orthogonally polarized parallel sub-beams, and a totally reflecting turning element which returns each sub-beam to the beam splitter along the path of the other sub-beam. A Q-switch is located in the path of one of the sub-beams. When the Q-switch is energized, the reflected polarization-shifted sub-beams are recombined at the splitter and pass through the lasing medium and adjacent partially-reflecting element as the output. When the Q-switch is deenergized, the sub-beams are dumped at the splitter which prevents the laser from oscillating.
