摘　　要：本文报导了最近研制成功的用于提高国产氩离子激光器相干长度的相干扩展器。利用这种基于Ｆ－Ｐ理论的相干扩展器可以使国产氩离子激光器的相干长度由不足５ｃｍ一下提高到ｍ的量级，功率损耗在２５％～４０％之间，有着很好的应用前景。The purpose of the paper is to introduce a coherence extender and the experimental study of the device. The extender is slanting Fabry-perot etalon.used in the resonator of the domestic argon-ion laser. With the coherence extender,the co-herence length of argon-ion laser can come from 5cm up to several meters and the power loss is the range of 25%～40%, The device can be used in the field of coherence detection.
