Degree of depolarisation of radiation from a single-frequency ring monolithic Nd3+:YAG laser with diode pumping

摘要

The degree of depolarisation of radiation from a single-frequency ring monolithic diode-pumped(chip) Nd3+:YAG laser was measured for the first time: its value was 3×10-3. The dominant mechanism of intracavity losses and of depolarisation of the output radiation was diffraction by random inhomogeneities of the birefringence of the active element.
