36 mu m dispersive mirrors compensating for dispersion introduced by the GaAs crystal

Chen, Yu; Hahner, Daniel und Pervak, Vladimir (2021): 36 mu m dispersive mirrors compensating for dispersion introduced by the GaAs crystal. In: Applied Optics, Bd. 60, Nr. 29: S. 9249-9253

Abstract

A new broadband dispersive mirror (DM), which consists of Si and SiO2 layer materials operating in the spectral range of 3-6 mu m, is developed for the first time, to our knowledge. The DM is able to compensate for the dispersion of a 0.5 mm thick GaAs crystal per bounce. Pulse analysis proves that the compensation effect of the DM is much better than a CaF2 plate, which is the commonly used dispersion compensation element in mid-infrared optical parametric oscillators (MIR OPOs), and the new MIR DM could improve the MIR OPO spectrum with better pulse quality and short pulse duration.
