Noiseless, quasi-phase-matched parametric amplifier in bulk lithium niobate

Autor: Lovering, D.J., Levenson, J.A., Vidakovic, P., Webjörn, J., Russell, P.St.J.

Although noiseless optical amplification has been demonstrated in bulk KTP crystals, and is well understood, there have been no observations of noiseless optical amplification in bulk quasi-phase-matched (QPM) systems. That such an amplifier is possi

Green-light generation of picosecond pulses in first-order quasi-phase-matched lithium niobate

Autor: Pruneri, V., Webjörn, J., Butterworth, S.D., Russell, P.St.J., Hanna, D.C.

Bulk periodically poled lithium niobate has been used for efficient first-order quasi-phase matched second harmonic generation of green light in the picosecond regime. We measured an effective nonlinear coefficient of ~14 pm/V.

Photorefractive scattering in bulk periodically poled lithium niobate

Autor: Pruneri, V., Kazansky, P.G., Webjörn, J., Russell, P.St.J., Hanna, D.C.

We report a new species of self-organised light-induced scattering, appearing only in bulk periodically poled lithium niobate. Clearly defined diffracted beams develop on exposure to 532 nm light from a frequency-doubled, Q-switched and mode-locked N

Tm3+ indiffused LiNbO3 waveguide lasers

Autor: de Sandro, J.P., Jones, J.K., Shepherd, D.P., Webjörn, J., Hempstead, M., Wang, J., Tropper, A.C.

We report the first room temperature laser operation of Tm3+:LiNbO3. The gain medium was a Ti-indiffused waveguide with active laser doping by thermal indiffusion. Lasing occurred at 1.85µm and results are presented for devices in single-domain, mul

Self-organised light-induced scattering in periodically poled lithium niobate

A new species of self-organized light-induced scattering, appearing only in bulk periodically poled lithium niobate, is reported. Clearly defined diffracted beams develop on exposure to 532 nm light from a frequency-doubled, Q-switched, and mode-lock

Thermally indiffused Tm3+:LiNbO3 waveguide lasers

Autor: Jones, J.K., de Sandro, J.P., Shepherd, D.P., Webjörn, J., Hempstead, M., Wang, J., Tropper, A.C.

Rare earth doped LiNbO3 is an interesting laser host as it has nonlinear, electro-optic and acousto-optic properties. Low-loss waveguides can also be made in this material and then combined with thermal indiffusion of the laser dopant. LiNbO3 can als

Low threshold singly resonant optical parametric oscillator in bulk periodically poled lithium niobate

Autor: Pruneri, V., Webjörn, J., Bollig, C., Russell, P.St.J., Hanna, D.C.

The development of periodically poled lithium niobate (PPLN) for quasi-phase-matched second order nonlinear applications has attracted much interest over the last few years. Compared to birefringence phase-matching, quasi-phase-matching (QPM) allows

Blue light generation in bulk periodically domain-inverted lithium niobate crystals

Autor: Webjörn, J., Pruneri, V., Russell, P.St.J., Barr, J.R.M., Hanna, D.C.

We report the generation of blue light in bulk domain-inverted lithium niobate by 3rd order quasi-phase-matching. High voltage pulses were used to induce periodic domain inversion in z-cut plates. The smallest domain width we have attempted to invert

Quasi-phase matching lithium niobate, periodically poled via liquid electrodes

Autor: Webjörn, J., Pruneri, V., Russell, P.St.J., Hanna, D.C.

We have achieved reliable periodic poling of z-cut lithium niobate in 0.2 mm thick samples, patterned with photoresist on one face and subjected to pulsed electric fields via liquid electrodes. Our set-up was a further development of the one used by
