  • Frequency converted laser sources and methods for operating frequency converted laser sources
    Patent number: 9223186
    Abstract: A method for operating a frequency converted laser source comprising at least one semiconductor laser and a wavelength conversion device optically coupled to at least one semiconductor laser may include operating the frequency converted laser source to produce a frequency converted output beam from the wavelength conversion device and intermittently heating the wavelength conversion device above a recovery threshold temperature TR of the wavelength conversion device. When the wavelength conversion device is heated above the recovery threshold temperature, the wavelength conversion device is held above the recovery threshold temperature TR for a period of time sufficient to restore output power lost to photo-degradation in the wavelength conversion device during operation of the frequency converted laser source.
    Type: Grant
