Fabrication of Thick Periodically-poled Lithium Niobate Crystals by Standard Electric Field Poling and Direct Bonding
نویسندگان
چکیده
We fabricated 1 mm-thick periodically-poled lithium niobate (PPLN) crystals by using a high-voltage amplifier for standard electric field poling combined with a voltage multiplier. Furthermore, two 1 mm-thick PPLNs were directly bonded to make a 2 mm-thick PPLN. The large aperture allowed broad angular tuning, and a broad spectral range of quasi-phase matched second-harmonic generation can be achieved in a single channel. High-power applications are also expected.

Nonlinear Integrated Optics with Periodically Poled Waveguides in LiNbO3
The advent of the electric field poling method to fabricate periodically poled, ferroelectric, nonlinear optical materials resulted in a renaissance of nonlinear optics. Since then quasi-phase matching has been used for efficient wavelength conversion in devices like frequency doublers, difference frequency generators (DFG) and optical parametric oscillators (OPO). Periodically poled Lithium Ni...
متن کاملDirect spectral phase retrieval of ultrashort pulses by double modified one-dimensional autocorrelation traces.
We propose and experimentally demonstrate an original method to analytically retrieve complete spectral phase of ultrashort pulses by measuring two modified interferometric field autocorrelation traces using thick nonlinear crystals with slightly different central phase-matching wavelengths. This new scheme requires no spectrometer, detector array, nor iterative data inversion, and is compatibl...

The tuning properties of pulsed narrowband THz radiation generated via optical rectification in periodically poled lithium niobate have been investigated. Using a disk-shaped periodically poled crystal tuning was easily accomplished by rotating the crystal around its axis and observing the generated THz radiation in forward direction. In this way no beam deflection during tuning was observed. T...
