Study of Temporal and Spatial Intensity Variations and Intracavity Damage Thresholds of Alexandrite Lasers

Source

The energy densities which can be obtained in a laser resonator before optical damage occurs are usually much lower than the optical damage thresholds measured in extracavity laser experiments. We have measured intracavity optical damage thresholds in an alexandrite laser operating in both single- and multitransverse mode and found the multitransverse mode laser has a much lower damage threshold. We studied the temporal and spatial variations of a multitransverse mode laser and found intensity hot spots which may be an important factor in the difference in the intracavity damage thresholds.
