__July 28__ Got a decent scan of the sample (Au) on the rubber isolation ring. The expansion rose greatly to about 5000 Å. This is definitely the expansion of the mica because the gold is only 1500 Å thick. A 5000 Å expansion correlated to about a 20ºC increase in temperature. Subsequently, a temperature increase of such magnitude would take about 30 seconds to reach with a 4 mW laser. This is a promising finding because this is the approximate time that the laser is on during the scan.
