    Mid-infrared frequency comb spectroscopy shines the way to dynamic process control of plasma nitriding.
    FIGURE 1. Schematics of a laser process based on population inversion and stimulated emission in a four-level gain medium (a) and optical parametric conversion in a nonlinear crystal (b). The process is subject to conversion of photon energy (wp = ws + wi) and photon momentum (kp = ks + ki).

    Extended wavelength coverage of OPOs advances studies on diamond-based quantum emitters.
    FIGURE 1. The parametric process in optical parametric oscillators (OPOs) can be perceived as splitting of an incoming pump photon of high energy into two photons of lower energy (usually denoted as signal and idler) and is subject to the conservation principles of photon energy and photon momentum.
