<p><P>PROBLEM TO BE SOLVED: To provide a parametric oscillator which is high in fundamental period stopping power and to which a resonator arbitrarily longer than the resonator of a light source for excitation is applicable and which is accompanied by recursive multiplication. <P>SOLUTION: The optical parametric oscillator is constituted to form signal light and idler light by incidence of exciting light pulses and to confine the signal light thereof into the resonator comprising a converging mirror 107, a end surface mirror 108, an output coupling mirror 509, and a converging mirror 505. The above oscillator is so constituted that the period T of an exciting light pulse train and the time (t) when the oscillation light pulses go around in the resonator of the optical parametric oscillator satisfy the relation t/T=M/N relating to two mutually prime natural numbers N and M (where M is neither 1 nor N±1). <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
