During the past year, a program to study the use of low density KC1 ~!y!lf&?S ' in direct relativistic particle detection systems2 was initiated at the Stanford Linear Accelerator Center. In the course of this study, a contradiction has been noted in data reported earlier by Sternglass and Wachtel,3 (hereafter denoted S and W). They measured an attenuation… (More)
In a high power fiber amplifier, a frequency-chirped seed interrupts the coherent interaction between the laser and Stokes waves, raising the threshold for stimulated Brillouin scattering (SBS). Moving the external mirror of a vertical cavity surface-emitting diode laser 0.2 μm in 10 μs can yield a frequency chirp of 5×10<sup>17</sup> Hz/s at a nearly… (More)
We report on the SBS threshold variations due to the coiling-induced birefringence in a non-polarization-maintaining fiber high power amplifier. We demonstrate that a control of the output polarization can permit higher SBS threshold operation.
