title: Efficient method for the extraction of second harmonic light after extracavity frequency doubling.
abstract: A method is given for the isolation of second harmonic radiation after extracavity frequency doubling of light from a synchronously pumped cw dye laser. The efficiency is close to 100%, and the original beam direction is restored.
