title: Intracavity gain detection: example I2, Br2.
abstract: Optical gains as small as 2 x 10(-5) are detectable by placing the gain medium inside the cavity of a cw dye laser and operating the laser slightly above threshold to take advantage of moderate spatial hole burning. This technique was used to measure gain on the 40' --> 6", 7", and 8" transitions in optically pumped Br2.
