+\section{Starting the Millenia V CW LASER.}
+
+The Millennia has problems with ‘thermal runaway’ upon startup if a user naively sends the laser to
+4.0 W in power mode (thermal runaway causes the infamous FAULT 146 system shut off, power adjust
+timeout error).  %
+The following procedure wakes the Millenia up gently enough to prevent thermal runaway.  %
+It assumes that the Millenia starts completely shutdown and cold.  %
+
+\begin{denumerate}
+  \item Check desiccant inside Millenia, replace if pink.
+  \item Ensure that Millenia shutter is closed such that no light is going downstream.  %
+  \item Flip orange power switch on diode box.
+  \item Wait for system to warm up ($\sim$30 minutes).
+    \begin{denumerate}
+      \item ``System Warming Up'' message should appear on control box.
+      \item Warm-up is finished when percentage complete indicator reaches 100.
+      \item The Millenia will start in SP Current mode.
+    \end{denumerate}
+  \item Record diode hours (choose ``Info'', scroll down).
+  \item Turn Millennia to 1.0 W in ``power mode'', wait for equilibration.
+\end{denumerate}
+
+
+Turn Millennia to 1.0 W in “power mode”, wait for it to equilibrate. This entails the diode temperature and current being stable (within 0.1) over 5 minutes.
+Turn Millennia to “current mode”.
+Slowly ramp current until you have ~4 W (or more) (~70%)
+Allow the diode temperature to stabilize while remaining in “current mode” (check every 5 minutes until it doesn't change by more than 0.1)
+Turn Millennia to 4.0 W “power mode”.
+Wait 10 minutes for extra assurance of equilibration.
+Ensure again that temperature and current are not changing (over ~5 minute timescale).
+Measure and record actual Millenia output power, currents, temperatures. 
+These data should be recorded in the GoogleSheet document for Millennia.
