<p>Zifang: </p> <hr /> <div>Offset Lock to phase modulate a pair of External Cavity Diode Lasers (ECDLs) separated by 6.8 GHz for manipulating between the hyperfine ground levels in Rb87.<br /> <br /> ===Project Plans===<br /> <br /> 1. Assemble two ECDLs.<br /> <br /> 2. Frequency stabilise one of the ECDLs to the Rb87 &lt;sup&gt;5&lt;/sup&gt;S&lt;sub&gt;1/2&lt;/sub&gt; &amp;rarr; &lt;sup&gt;5&lt;/sup&gt;P&lt;sub&gt;3/2&lt;/sub&gt;.</div>
