Abstract:

For operating at the CO2 laser wavelength (10.6 mu m), we manufactured single- and double-layered infrared (IR) fibers, as well as those with an enlarged mode field diameter, obtained via extrusion from Ag(Cl) (x) Br1 - x (0 < x < 1), Ag1 - x Tl (x) Br1 - x I (x) (0 < x <= 0.08), Ag1 - x Tl (x) Cl (y) I (z) Br1 - y - z (0.003 <= 0.040; 0.066 <= 0.246; 0.004 <= 0.048) crystals. We calculated their fundamental characteristics at 10.6 mu m and conducted computer simulation of their structure and mode field beforehand. Optical and mechanical characteristics of IR crystals and fibers, such as transmission range, refractive indices, and durability, were also determined, with the dependence of varying monadic thallium iodide content on them being shown as well. In particular, we demonstrated that the increase of thallium iodide content in the initial silver chloride bromide widens the transparency range to 40 mu m and improves the rupture strength up to 200 MPa, which is due to the decrease in average fiber grain size up to 95 nm-nanocrystalline size. Using a CCD camera for the far field investigation at 10.6 mu m, we showed the single mode of the fibers obtained.
