LASER LIGHT SOURCE DEVICE ABSTRACT OF THE DISCLOSURE The present invention discloses a laser light source device having a laser and an external resonator, wherein a Faraday rotator is provided as a base at the front side of a laser of a reflection plane of the resonator, so that clockwise and counter-clockwise circular polarizations, which have slightly different frequencies to each other, are generated. If a laser, such as a semiconductor laser, is arranged to have an eigen-mode with a linear polarization, a pair of elements can be employed for rotating a polarization by 90 degrees by one emission-and-return through an element, for example, quarter-wave plates. The device does not require strong magnetic or electric fields, and can easily generate lights which are a constant strength. Thus the device can be miniaturized and high efficiency can be obtained.
