Abstract:
A variable wavelength laser light source comprising:a laser for producing light and having first and second faces for light output;a first optical reflector located to one side of one output face of said laser and having a reflecting surface to receive light;a diffraction grating located to one side of the other face of said laser to select and output at a selected wavelength light received from said other face of said laser;a second optical reflector which receives and reflects the light outputted from said diffraction grating, said second optical reflector forming an optical resonator with said laser and said first optical reflector;a first rotating mechanism to which said second optical reflector is mounted which rotates said second optical reflector around an axis of said first rotating mechanism; anda second rotating mechanism which rotates said second optical reflector around a second axis located remotely of said second optical reflector.
