Abstract

A picosecond double-pass periodically poled KTiOPO4 (PPKTP) noncollinear parametric amplifier that delivers tunable and narrowband outputs between 1.1 µm and 1.65 µm is reported. The seed source is an ultra-broadband emitting PPKTP collinear parametric generator, which is spectrally narrowed, from a bandwidth of 80 THz to about 0.3 THz, by a Fourier-filtering arrangement. A parametric gain of 70 dB is measured with preserved spectral bandwidth, resulting in a signal energy of 6.5 µJ at a pump energy of 60 µJ from the Ti:sapphire regenerative amplifier. The total energy-budget for the setup is less than 100 µJ with an optical-to-optical efficiency of 12 %. This particular system is scalable to even lower pump energies by tighter focusing arrangements.

The experimental setup consists of an OPG-stage (top) and an OPA-stage (right bottom). The seed is spectrally manipulated in the “black-box” and thereafter launched into the OPA. The pump for the OPA-stage is delayed and the power output is adjusted with the λ/2-wave plate (WP) and the Glan polarizer (GP).

(a). Measured amplified central wavelength as a function of the time delay of the OPA pump beam. (b). The output spectra. The grey curve is the OPG output spectrum. Dashed curve: at a delay of 1 ps. Dotted curve: at a delay of 4 ps. Dotted-Dashed: at a delay of 7.3 ps.

Modified experimental setup. The OPG seed is spectrally manipulated in a zero-dispersion arrangement. The seed’s polarization is rotated with the λ/2-wave plate (WP) in order to maximize the diffraction efficiency into the minus first-order of the grating.

(a). Grey curve is the OPA crystals gain spectrum. Black curves: tuning of the seed by moving the aperture in the FP. (b) Single-pass amplified spectrum. A central wavelength of 1497 nm, with a preserved bandwidth of 2.2 nm (FWHM). The spectrum is diffraction-limited, due to the slit-aperture in the Fourier plane.

The second-pass experimental setup. The signal and the pump propagate off-axis through the lens fs and the mirrors M1 and M2 displaces the beams when returning for a second-pass through the PPKTP crystal.
