Abstract
Two different adjustable repetition rate optical frequency combs were designed and constructed with off-the-shelf components, including several improvements to established erbium fiber designs. These designs were assembled at a fraction of the cost of a commercial comb. Both combs were constructed with a repetition rate of roughly 100 MHz, with one combs tuning range being 2 MHz and the others being 3 MHz. These combs followed different designs, the first being a modification of an established nonlinear polarization rotation (NPR) design, the second being a modification to a “figure 9” design. A stabilization control loop for frep achieved long-term drifts of < 1 Hz over several days. The second comb will eventually be implemented for use in dual-comb spectroscopy. This dual-comb setup will be tested on hydrogen cyanide before its use to take the high-resolution spectrum of benzene.
