Relative contribution of the electric-field-induced third-order effect to second-harmonic generation in poled, doped, amorphous polymers

Received October 6, 1992; revised manuscript received October 4, 1993; permission to publish received July 6, 1994 A novel approach involving a delay-trigger method and doped, glassy polymers has been developed to determine the contribution of the electric-field-induced third-order effect to the second-order macroscopic susceptibility x(2) of nonlinear optical dyes. A submillisecond, variable t...

Generation of tunable green radiation in bulk periodically poled KTiOPO4

We report a characterisation of a flux-grown periodically poled KTiOPO4 crystal used for second-harmonic generation in a diode laser source, that operates with fundamental radiation tunable around 1083 nm wavelength. The conversion efficiency is measured for the three different grating periods of the crystal, as a function of input wavelength, crystal temperature and fundamental power. The meas...

Ultra-broadband optical parametric generation in periodically poled stoichiometric LiTaO3.

We report on broadband gain in an optical parametric generator based on periodically poled 1 mol% magnesium-doped stoichiometric LiTaO3 (PPMg:SLT). More than an octave-spanning parametric gain, stretching from near to mid-infrared, is generated by pumping the crystals close to the point where, at parametric degeneracy, the waves experience zero group-velocity dispersion. Using a picosecond Ti:s...

Noncollinear second-harmonic generation in sub-micrometer-poled RbTiOPO(4).

We have generated noncollinear quasi-phase-matched second harmonic wave in an RbTiOPO(4) crystal that was poled using the high-voltage atomic force microscope (HV-AFM). To the best of our knowledge, this is the first systematic nonlinear frequency conversion study of samples produced by the HV-AFM method. The short poling period of 1.18 microm enabled us to observe second harmonic generation at...

Periodically Poled KTiOAsO4 For Mid-Infrared Light Generation

A periodically poled KTiOAsO4 crystal was fabricated at room temperature. The poled crystal shows a deff of 10.1 pm/V and gives a parametric conversion efficiency of 45%. ©2010 Optical Society of America OCIS codes: (160.2260) Ferroelectrics; (190.4410) Nonlinear optics, parametric processes
