Electro-optical shutters technique in q switching

In my earlier articles I have discussed the basics of Q-switching and three of its techniques known as mechanical shutters, rotating reflector method and passive shutters. Toady I will discuss the one more following techniques of Q-switching:

Electro-optical Shutters.

To obtain faster switching, the suitable electro-optical effects of altering the refractive index of a cell by applying an electic field is used. Two such effects are:

i)   Pockels effect

ii)  Kerr effect

i) Pockels effect. Continue reading “Electro-optical shutters technique in q switching”
