## Abstract ## Background and Objectives Endoscopic applications of the Erbium:YAG laser have been limited due to the lack of a suitable optical fiber delivery system. The purpose of this study was to compare the transmission of Er:YAG laser radiation through germanium oxide trunk fibers with sili

## Abstract The longβpulse (200β350 ΞΌs) Holmium: YAG (Ho: YAG) laser (Ξ» = 2.12 ΞΌm) is used extensively in urology for laser lithotripsy. The longβpulse Erbium: YAG (Er: YAG) laser (Ξ» = 2.94 ΞΌm) fragments urinary calculi up to 5 times more efficiently than the Ho: YAG laser, however, no optical fibe
## Abstract ## Background and Objectives Endoscopic applications of the erbium (Er):YAG laser have been limited due to the lack of an optical fiber delivery system that is robust, flexible, and biocompatible. This study reports the testing of a hybrid germanium/silica fiber capable of delivering E
