Polarizer NLO Crystals Waveplate High Power Polarization Beamsplitter EO Q-Switch

KD*P EO Q-Switch

E-O Q Switch alters the polarization state of light passing through it when an applied voltage induces birefringence changes in an electro-optic crystal such as KD*P. When used in conjunction with polarizers, these cells can function as optical switches, or laser Q-switches. 

Our EO Q-switch employs the finest strain-free, highly deuterated KD*P available. Based onadvanced crystal fabrication and coating technlogy, we can offer a variety of laser wavelengths EO Q switchs which exhibits high transmission (T>97%), high damaged threshold (>500W/cm2 )and high extinction ratio (>1000:1).
