Abstract
A method and a device for generating visible coherent radiation is disclosed. The visible coherent radiation is generated by sum-frequency mixing of a first fundamental beam from a diode laser and a second fundamental beam from a diode-pumped solid-state laser. The mixing is performed by means of a quasi-phasematching element provided within the resonant cavity of the solid-state laser. The first fundamental beam is stabilized by providing feedback to the diode laser.
