Embodiment Construction
[0023] We recently proposed an erbium amplifier to amplify femtosecond pulses from a 1580nm femtosecond fiber laser. This is described in US Patent Application No. 11 / 105850, filed April 4, 2005, incorporated herein by reference. The amplifier works under the principle of self-similar transmission, and the output of the amplifier is a highly extended pulse with a nearly linear frequency modulation pulse. A schematic diagram of this amplifier is shown in FIG. 1 , where the output of the laser 11 is directed through a fiber amplifier 12 . For the purposes of this work, pulse quality Q is defined as the ratio of the central (strongest) pulse energy to the energy contained in the entire pulse, including any reference or auxiliary pulses. An illustration of these definitions is shown in Figure 2. The main pulse body is shown at 21 and the reference pulse at 23 . The half-maximum point of the full pulse width is shown at 22 . An ideal pulse has a Q of 1. A high Q value is an im...
