Series 1145 Q-switches are miniature electro-optic devices (Pockels cells) intended for use with the latest compact size lasers. They are useful for Q-switching, cavity dumping and laser pulse extraction in regenerative amplifiers. Other applications include polarization rotation, laser beam chopping,slicing and pulse picking. They accommodate the most demanding high peak power laser applications. All models within the series utilize a rugged internal crystal support and hermetic sealing system. The devices incorporate highest quality crystals, fused quartz windows and high damage threshold antireflection coatings.
