Abstract
GeSeTe and GeAsSe glass fibers with core-cladding structure were prepared by a crucible drawing method. The transmission losses at 10.6 im were 1.8 - 2.2 dB/m cor GeSeTe fibers and 5.2 - 5.5 dB/m for GeAsSe fibers. The power transmission characteristics of C02 laser(1O.6 jim) through these fibers were investigated. The power up to 4.6 W(2.9 kW/cm2) could be transmitted through the GeSeTe fiber of 100 cm long. The output power through the GeAsSe fiber(100 cm) was less than 2.2 W(1.4 kW/cm2 ). In each case, the core area was apt to be fused when the output power exceeded these values. Cooling of fiber was effective to suppress such damage. The power of 20 W could be launched into the GeSeTe fiber cooled by water and the output power of 6.5 W(4.1 kW/cm2 ) was obtained. The transmission efficiency was considerably improved by the antireflection coating of PbF2 onto the fiber ends. The output power of 10.7 W(6.7 kW/cm2) was attained when the GeSeTe fiber with PbF2 coating was cooled by water.
