| Summary: | We present the successful development of a new fibre laser system for a laser-wire electron beam emittance diagnostic, suitable for intra-train scanning in an ILC-specification environment. The system is based on the amplification of a commercial Ytterbium (Yb) fibre laser with a repetition rate of 6.49MHz in rod type Yb doped photonic crystal fibre (PCF). We demonstrate world leading laser performance, with amplification of pulses from 1.5μJ to 268μJ and a beam quality factor M2 < 1.1, in 1ms bursts at 2Hz. Copyright © 2011 by IPAC'11/EPS-AG. |
