Abstract
KRS-5 (TlBr-TlI) fiber for high power transmission has been developed. The most preferable composition for the fiber has been investigated to be 43 weight % TlBr, and under this composition the fiber with 0.5 mm diameter and 1.5 m length has excellent characteristics as follows. (1) High output power of 70 watts, (2) high transmissibility of more than 90%, (3) minimum bend, radius of 10 cm.
This fiber has been put into practical use for CO2 laser scalpel. The scalpel has almost same incision capability and excellent flexibility in comparison with mirror joint CO2 laser scalpel.
