More info

Lanthanum Gallium Silicate (LGS) Electro-Optic Q-Switch is a high-performance device designed for modulating laser pulses in medium-energy laser systems. Utilizing LGS crystal, this Q-switch offers a significantly higher damage threshold—approximately nine times that of LiNbO3—along with excellent electro-optic coefficients and outstanding temperature stability. It serves as a practical electro-optic component, partially replacing DKDP, RTP, and LiNbO3 Q-switches in various laser applications. Heeger Materials provides high-quality LGS Electro-Optic Q Switches for stable and efficient laser modulation.
