Advances in all-solid-state intracavity-frequency-modulated lasers

Tunable all-solid-state lasers are increasingly employed, and there has not been a relatively comprehensive paper discussing these lasers. This paper will describe several frequencymodulation approaches applied to the tunable all-solid-state single-longitudinal-mode laser, including their characteristics and researches. It could be hoped to provide a reference for those researchers about intracavity frequency modulation in all-solid-state lasers.
