Abstract

We report on measurements of the frequency noise of a highly stabilized injection locked Nd:YAG laser. We use a nested loop frequency stabilization scheme to achieve a loop gain of approximately 1×10<sup>6</sup> at Fourier frequencies around 1 kHz with frequency actuation applied only to the master oscillator. A frequency noise level of approximately 2×10<sup>-5</sup> HzHz<sup>-1/2</sup> was measured for the master laser around this frequency using an independent, narrow line width, suspended analyzer cavity. Furthermore we demonstrate that the frequency noise performance of the injection locked slave laser is identical to that of the master oscillator to this level. This performance is very close to the frequency noise specification for gravitational wave detection by GEO 600.
