Response to 'Comment on GaSe_(1-x)S_x and GaSe_(1-x)Te_x thick crystals for broadband terahertz pulses generation' [Appl. Phys. Lett. 100,136103 (2012)]

摘要

In our paper, we reported that doping of GaSe with S and Te reduces the absorption peak at 0.59 THz. In the comment2 on our paper, Ku et al. suggested that the appearance of the absorption resonance near 1.8 THz in these doped crystals is to be taken into consideration as it could make the broadband THz generation impossible. This phonon resonance is indeed present in mixed GaSe_(1-x)S_x and GaSe_(1-x)Te_x crystals, and we provide an additional accurate measurement of this absorption peak here (Fig. 1(a)).
