Abstract

PURPOSE:To provide a circuit of small size, which has a simplified construction and which is capable of narrowing the pulse width of any light, by providing first and second double refractive substances, a phase shifter which is operative to shift the phases of two beams, and an analyzer at the outlet end faces of the second double refractive substance.
