Abstract

A laser apparatus includes a fiber oscillator. In another aspect, an Ytterbium (Yb) doped fiber is employed. Another aspect provides an unamplified laser pulse emitted from an Yb fiber oscillator having a repetition rate less than 5 MHz and a pulse energy greater than 100 nJ. In still an additional aspect, a flexible Yb fiber has a length greater than 1 m which is capable of being looped with an outside loop diameter less than 150 mm. Another aspect provides for a fiber oscillator with passive optical fiber lengths of at least 10 meters, and more preferably more than 100 meters while having repetition rates less than 4 MHz.
