Abstract: A multiple-wavelength ultrashort-pulse laser system includes a laser generator producing ultrashort pulses at a fixed wavelength, and at least one and preferably a plurality of wavelength-conversion channels. Preferably, a fiber laser system is used for generating single-wavelength, ultrashort pulses. An optical split switch matrix directs the pulses from the laser generator into at least one of the wavelength conversion channels. An optical combining switch matrix is disposed downstream of the wavelength-conversion channels and combines outputs from separate wavelength-conversion channels into a single output channel. Preferably, waveguides formed in a ferroelectric substrate by titanium indiffusion (TI) and/or proton exchange (PE) form the wavelength-conversion channels and the splitting and combining matrices. Use of the waveguide allows efficient optical parametric generation to occur in the wavelength-conversion channels at pulse energies achievable with a mode-locked laser source.

Abstract: A high gain optical parametric amplifier is implemented in a LiNbO3 waveguide fabricated by a combination of periodic electric field poling and proton exchange techniques. The device is capable of amplification in the whole transmission window of silica optical fibers with gains up to 90 dB. The high nonlinearity and resultant high gain of the waveguide-amplifier permits the use of essentially standard power (milliwatt to 10 watt) fiber laser pump sources.
