Highly efficient second harmonic generation (SHG) vertical external cavity surface emitting laser (VECSEL) system
A Vertical External Cavity Surface Emitting Laser (VECSEL) system is provided. The VECSEL system includes a laser device including an active layer in which laser light is generated by pumping and a reflector reflecting the laser light generated in the active layer; an optical element that forms a cavity together with the reflector of the laser device and reduces a line width of laser light; and a SHG (Second Harmonic Generation) device that is disposed between the laser device and the optical element and doubles the frequency of laser light.
