Title: Variable-wavelength laser device and method for specifying wavelength of laser beam thereof
Inventor: YOROZU MASAFUMI
IPC: H01S3/13
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To easily specify the absolute wavelength of a variable-wavelength laser device by comparing a specific exciting wavelength at which a reference gas emits fluorescence with a fluorescence intensity distribution obtained through an observation process. SOLUTION: When a control signal (s) is sent to a variable-wavelength laser light source 10 from a controller 40, a control means 40 scans the oscillation wavelength of the light source 10 and changes the relative wavelength of a control signal (s) and, at the same time, receives the fluorescence intensity corresponding to each relative wavelength from a photodetector 30 and obtains the fluorescence intensity distribution to the relative wavelength. Then the control means 40 finds the position where all peaks overlap the peak of a reference fluorescence distribution by comparing the obtained fluorescence intensity distribution with the reference fluorescence distribution and shifting the fluorescence intensity distribution to the relative wavelengths along the coordinate axis of an excited wavelength.  Therefore, when the control means 40 is made to store the relative wavelengths and corresponding absolute wavelengths by correlating them with each other, the absolute wavelength of the laser beam outputted from the laser source 10 can be specified with high accuracy.
