Abstract

We describe the use of an asymmetric feedback ring in an unstable resonator to obtain arbitrarily narrow-linewidth radiation across the full available aperture. We demonstrate its use with an electric-discharge XeCl laser to produce single-line radiation with a linewidth of 0.15 cm−1.

Fig. 1
Fig. 1

Schematic diagram of narrow-bandwidth unstable resonator using an asymmetric feedback ring. Collimated light traveling counterclockwise in the ring is frequency narrowed by the FP étalon. Most of the diverging light traveling in the clockwise direction is blocked by the aperture at the focus of the lens.

Fig. 2
Fig. 2

(a) Output beam profile (left) and ring pattern from a FP interferometer (right) obtained from the unstable resonator with the asymmetric feedback ring with a single 99-μm air-spaced étalon in the cavity. (b) Output beam profile (left) and diode array measurement of outer FP rings (right) obtained from the unstable resonator with an asymmetric feedback ring with the 99-μm étalon and a 5-mm solid étalon. The free spectral ranges of the interferometers used for (a) and (b) are indicated, and their finesse was ~15.

Fig. 3
Fig. 3

Schematic diagram of a linear unstable resonator with étalons for frequency narrowing. One étalon sees collimated light traveling from right to left and diverging light traveling from right to left. The second étalon sees converging light on both passes.

Fig. 4
Fig. 4

Output beam profiles (left) and ring patterns from FP interferometers (right) obtained with the radiation from the linear unstable resonator shown in Fig. 3 when (a) one 99-μm air-spaced étalon was used in the cavity and (b) the 99-μm étalon and a 5-mm solid étalon were used. The ring pattern in (b) was obtained from the bright region across the center of the pattern at the left. The spectral distribution shows a dominant narrow-band component accompanied by a lower-intensity broadband component.
