Time characterization of a thermal lens using a differential interferometric technique

Abstract:

We present a method for measuring weak absorption in optical materials, using a new diferential interferrometry technique. Both thermal shift phase and thermal characteristic time may be determined by fitting the observed time-resolved interferometric signal.
