| titleOfInvention | Tunable laser light source and controlling method of the same |
| abstract | The objective of the present invention is to provide with a tunable laser light source and controlling method of the same capable of detecting the degree of out-of-tune-ness, maintaining simple configuration. The tunable laser light source comprises a gain medium 1, a tunable band rejector 2, an etalon 3, and a transmitted light detector 4. The gain medium 1 is capable of amplifying light within a wavelength band including a target wavelength. The a tunable band rejector 2 is positioned opposite the gain medium thereby forming an edge of a laser resonator and is capable of rejecting light with a certain wavelength tunable to the target wavelength from the incident light emanating from the gain medium while transmitting the remaining. The an etalon 3 is positioned between the gain medium and the tunable band rejector and is capable of selectively transmitting light with certain wavelengths including the target wavelength. The a transmitted light detector 4 is positioned to the place where its incident light enters through the tunable band rejector and is capable of detecting the power of the light. The tunable laser light source 100 may further comprise an optical coupler 5, a beam splitter 6, and a branched off light detector 7. Here, the optical coupler 5 is capable of coupling with the laser beam emanating from the gain medium 1. The beam splitter 6 branches off a part of this laser beam. The branched off light detector 7 consists of such as a photodiode and is capable of detecting the beam branched off by the beam splitter 6. |
