Phase-matched second-harmonic generation by eriodic poling of fused silica
نویسندگان
چکیده
90” phase matching in periodically poled fused silica is achieved over approximately 2 mm at a wavelength of 1064 nm. Electrical poling was done at 5 kV for 120 min using photolithographed periodic electrodes on fused silica glass at 250 “C. A nonlinearity equivalent to &/200 of quartz is estimated from measurements. Several phase-matched interactions are reported and the implications for device applications discussed.

Quasi-phase matched second-harmonic generation through thermal poling in femtosecond laser-written glass waveguides.
Quasi-phase matched second-harmonic generation at 532 nm is demonstrated in a channel waveguide that is written in bulk fused silica using a femtosecond laser. The second-order nonlinear grating is fabricated using uniform thermal poling followed by periodic erasure inside an e-beam deposition system caused, by what we believe to be, x-rays. A SHG conversion efficiency of 2 x10(-5) %/W-cm(2) wa...

Second-order optical properties of thermally poled arsenicgermanium sulfide glasses have been investigated. Parallel studies of glass structure changes upon poling and/or visible cw-laser irradiation and complete SHG quantitative analysis have been performed. Key parameters and poling mechanisms influencing largely SHG stability and efficiency have been pointed out. ©2013 Optical Society of Ame...
متن کاملThermal poling of glass modified by femtosecond laser irradiation
Thermal poling of silica glass modified by femtosecond laser irradiation is demonstrated. Increase of second-harmonic generation in the irradiated regions is observed. This enhancement is interpreted in terms of structural modifications in silica glass that make the poling process more efficient. Evidence of a change in the distribution of the electrostatic field frozen in glass during poling i...
متن کاملNoncollinear 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...
متن کاملTunable ultraviolet radiation by second-harmonic generation in periodically poled lithium tantalate.
We describe electric-field poling of fine-pitch ferroelectric domain gratings in lithium tantalate and characterization of nonlinear-optical properties by single-pass quasi-phase-matched second-harmonic generation (QPM SHG). With a 7.5-microm-period grating, the observed effective nonlinear coefficient for first-order QPM SHG of 532-nm radiation is 9 pm/V, whereas for a grating with a 2.625-mic...
