摘要	PURPOSE:To facilitate control of the width of a spectral line, by providing a reflection type filter, which feeds back rear emitting light of a laser to the laser, at a distance that is integer times the wavelength to be selected among laser light rays, and forming an external cavity. CONSTITUTION:Any of laser light rays having a plurality of wavelengths from a laser device 2 is selectively reflected by a reflection type filter 8. For example, the distance between the laser device 2 and the reflection type filter 8 is set at the length integer times the central wavelength of the laser light rays, and the light ray is reflected. With respect to only this reflecting component, the phase of the laser light, which is inputted into the laser device 2 from an external cavity 13 formed with the laser device 2 and the reflection type filter 8, is optimized, and oscillation occurs. Said component is made to be the laser light, which is outputted from the laser device 2. Namely, the laser light having the single wavelength is obtained. The width of the spectral line of the laser light having the single wavelength can be made narrow by the extension of the distance. When the setting conditions are misaligned, the conditions are recovered with an optical pathlength adjusting means 10.
其他摘要	目的：为了便于控制光谱线的宽度，通过提供反射型滤光器，该滤光器将激光的后发射光反射到激光器，其距离是激光光线中选择的波长的整数倍，并形成一个外腔。组成：任何来自激光设备2的具有多个波长的激光光线被反射型滤波器8选择性地反射。例如，激光设备2和反射型滤波器8之间的距离设置为整数倍的长度激光光线的中心波长和光线被反射。仅对于该反射分量，优化从由激光器件2和反射型滤波器8形成的外腔13输入激光器件2的激光的相位，并且发生振荡。所述部件被制成激光，其从激光装置2输出。即，获得具有单一波长的激光。通过距离的延长，可以使具有单一波长的激光的光谱线的宽度变窄。当设定条件未对准时，利用光程长度调节装置10恢复条件。
