Abstract
BaLiF3 crystals doped with transition metal ions are potential new las er active media. Thermal diffusivity of a pure BaLiF3 crystal was dete rmined at room temperature using the photoacoustic two-beam phase lag method, which consists in measuring the relative phase-lag for the pho toacoustic signal between rear and front surface illumination at a sin gle modulation frequency.
