One example is lead lanthanum zirconate titanate, a transparent ferroelectric ceramic whose optical properties can be changed by an electric field.
In lasers, such materials can be used for beam deflection, beam modulation, and Q switching (a switch that allows for the build-up of energy before it is switched open to allow light to move out).
One example is lead lanthanum zirconte titanate, a transparent ferroelectric ceramic whose optical properties can be changed by an electric field.
In lasers, such materials can be used for beam deflection, beam modulation, and Q switching (Quality switch or an optical valve in a laser that prevents light from transmitting outside the resonating cavity).
The Q switch allows for the build-up of energy before it is switched open to allow light to move out.
