ABSTRACT:
An improved optical glass fiber for transmitting mid infrared wavelength laser light in surgical instruments, includes a heavy-metal oxide component, preferably GeO.sub.2 doped with heavier cations and anions, and which is capable of delivering at least three watts of laser power continuously for more than ten minutes, without failure. This glass fiber has an .alpha.(dB/m) at 2.94 .mu.m of 10, preferably less, and can transmit at least 27% of the IR through a thickness of one foot.
