摘要： Optical systems operable to emit multiple frequency- converted spectral peaks are provided. In one embodiment, an optical system (100) includes an optical source (110) and a wavelength conversion device (130). The optical source (110) may include a laser configured to emit a pump beam (120) having at least two fundamental spectral peaks (125, 127). The wavelength conversion device (130) may include a non- linear optical medium configured to phase match the second harmonic generation of each of the at least two fundamental spectral peaks (125, 127) and sum- frequency generation of the at least two fundamental spectral peaks (125, 127) such that an output beam (140) comprising at least three frequency- converted spectral peaks (142, 144, 146) having approximately equal power is emitted from an output facet (138) of the wavelength conversion device (130) when the pump beam (120) of the optical source (110) is incident on an input facet (131) of the wavelength conversion device (130).

摘要： A method for operating a wavelength-converted light source includes directing a pump beam having a fundamental wavelength from the laser source into an input facet of the wavelength conversion device such that a wavelength-converted output beam is emitted from an output facet of the wavelength conversion device in the field of view of an optical detector. A physical property of the wavelength conversion device is varied within individual ones of a succession of consecutive speckle reduction intervals having durations less than the integration time of the optical detector. The physical property of the wavelength conversion device is varied by an amount that is sufficient to change in a phase-matched (PM) wavelength of the wavelength conversion device. The fundamental wavelength of the pump beam is thereafter adjusted based on the change in the PM wavelength to maintain an efficiency of the wavelength conversion in the wavelength conversion device.

摘要： A method for operating a frequency converted laser source comprising at least one semiconductor laser (110) and a wavelength conversion device (120) optically coupled to at least one semiconductor laser (110) may include operating the frequency converted laser source to produce a frequency converted output beam (128) from the wavelength conversion device (120) and intermittently heating the wavelength conversion device above a recovery threshold temperature T R of the wavelength conversion device. When the wavelength conversion device is heated abo.ve the recovery threshold temperature, the wavelength conversion device is held above the recovery threshold temperature T R 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. The heater (160) is controlled by a MC (150) and is for example attached to the waveguide (124) of a MgO : PPL with a recovery temperature of 70°C.
