Wereporton a method for delivering high fluence pulsed 266\text{\hspace{0.17em} nm} laser radiation to the target tissue via an optical fiber. The fourth harmonic of a Nd:YAG laser was concentrated using a hollow glass taper and launched into an optical fiber. Fluences of up to 2\text{J}/{\text{cm}}^{\text{2}} were routinely output at the tapered optical fiber tip. The maximum fluence generated before failure of the optical fiber was between 3.5 and 8\text{J}/{\text{cm}}^{\text{2}} . Ablation of ocular tissue was demonstrated using fluences of 1.0 and 0.4\text{J}/{\text{cm}}^{\text{2}} . The delivery system has the potential for use in intraocular surgicalprocedures.
