摘要：

We report on the development of hollow-core photonic bandgap fibers for the delivery of high energy pulses for precision micro-machining applications. Short pulses of (65ns pulse width) and energies of the order of 0.37 mJ have been delivered in a single spatial mode through hollow-core photonic bandgap fibers at 1064nm using a high repetition rate (15kHz) Nd:YAG laser. The ultimate laser-induced damage threshold and practical limitations of current hollow-core fibers for the delivery of short optical pulses are discussed. (C) 2004 Optical Society of America.
