Hollow glass fibers for delivery of mid-infrared lasers are drawn from a glass-tube preform to produce a long and flexible hollow fiber at low cost. To utilize the interference effect of the thin glass wall, the wall thickness is controlled by the drawing speed. A Pyrex-glass hollow fiber with an inner diameter of 280 (μm and a wall thickness of 9.92 μm shows a low loss at 2.94 μm of the Er:YAG laser wavelength when coated with a silver film on the outer surface.
