| 摘要 |
The present invention refers to a device for generating frequency doubled laser light by means of quasi-phase matching, comprising a laser diode; a frequency doubling waveguide formed in a non-linear optical element with a quasi-phase matching grating; and a stabilizing grating which provides frequency stabilizing feedback to the laser diode. The invention is characterized by an optical fiber coupled to the active region of the diode laser and connected to the waveguide in the non-linear element, wherein light being emitted from the active region of the laser diode is transferred through the optical fiber to the waveguide, whereby efficient and stable light transfer is achieved. |
