    摘要: A tunable narrowband source of a coherent radiation, comprisinga first optical parametric oscillator (OPO1) which includes at least one first optical parametric amplifier medium (K.sub.1) in a resonator (18, 20; 20, 34) or an optical parametric generator;at least one second optical parametric oscillator (OPO2) which includes at least one second optical parametric amplifier medium (K.sub.2) in a resonator (22, 24) and into which is coupled the output radiation (28; 28b) of the first optical parametric oscillator (OPO1);at least one third optical parametric amplifier medium (OPA) into which is coupled the output radiation (30) of the second optical parametric oscillator (OPO2); andmeans (12, 14, 16, 26) for generating and coupling the pump radiation (10, 10') into the first and second optical parametric oscillators (OPO1, OPO2) and into the third optical parametric amplifier medium OPA), whereinthe output radiation (28; 28b) of the first optical parametric oscillator (OPO1) which is coupled into the second optical parametric oscillator (OPO2) has a bandwidth which is smaller than the spacing of the only one longitudinal mode is excited and coupled into the third optical parametric amplifier medium (K.sub.3, K.sub.4) and amplified therein.
