Abstract

We report on a new periodically poled lithium niobate grating design with a continuous grating-period change (fan-out). We observed 350 cm-1 (80  nm at 1.5 µm) of complete spectral coverage at a constant temperature in a cw optical parametric oscillator. Complete spectral coverage is demonstrated by measurement of an absorption band of CO2.

Fig. 1

Exaggerated view of the fan-out pattern on the PPLN crystal. The arrows on the side of the crystal indicate the poling direction. For the OPO the pump, signal, and idler beams are polarized along the crystallographic z axis (as indicated by the coordinates at the lower right), and they propagate along the x axis (as indicated by the large arrows entering and leaving the crystal), sampling only one periodicity.

Fig. 2

Experimental setup for the cw PPLN OPO with the fan-out crystal. We used the output of the signal to measure the transmission through an 8-m multipass cell containing CO2 at 15  Torr.

Fig. 3
Fig. 3

Signal output power as a function of frequency for the cw OPO at a fixed temperature and grating periodicity. Tuning was accomplished by rotation of the intracavity etalon. The power drop is due to tuning away from the peak of the grating bandwidth. The frequency range corresponds to 1577±0.8 nm.
